Conferences-and-Events

This is a written version of my 5-minute talk from the Indie Soapbox session at this year’s GDC. Why are you making games? No, I don’t mean “why are you making games?”. Also, I don’t mean “why are you making games?”. And I certainly don’t mean “why (on earth) are you making games?”. I mean the question in the purest, most abstract sense. Just “why are you making games?”. This was a key question for me last year, I spent a lot of time thinking about it, and I thought other people might benefit from asking themselves the same question. To see where I’m coming from, let’s do a quick flash back. It’s late 2011. Miguel and I finished working on Casey’s Contraptions and my daughter was born. I took a couple months completely off from work (new dads will understand why), and then, right at the turn of the new year, I decided to start working again. The plan was to prototype a few of the juiciest ideas, pick one that really stood out, and make a new game in a few months. How hard could it be, right? Right? ...

A few days ago I gave a talk at Evolve 2011 (part of the Develop Conference in Brighton, England) titled “One Price Does Not Fit All”. The main idea of the talk was the importance of “flexible pricing”: Letting players spend as much money as they want to get more enjoyment out of the game and customize their play experience. Flexible pricing can result in revenues much higher than the traditional fixed price approach (derived from manufactured goods). It’s also orthogonal to the concepts of freemium and social games, and we’re only scratching the surface in ways to effectively implement it in games. Here’s the official conference abstract: Did the biggest fans of your game spend more money on it than someone who played it just a few times? If not, you’re leaving a huge percentage of money on the table. This session will talk about how digital distribution has made fixed prices obsolete and how you can take advantage of flexible pricing through in-app purchases in your games. We’ll also talk about the consequences (good and bad) of making a game free to play. The session will present hard data from iOS platforms, but applies to all digital distribution platforms. ...

About 48 hours ago, I participated in the 360iDev Game Jam. I’m still recovering from the sleep deprivation and caffeine excesses, but here are some random thoughts about the game jam and why I highly recommend the experience to all developers. This was my third 360iDev Game Jam, and it gets better all the time. It’s great to see that it has become a 360iDev tradition, and that the number of people participating is going up every time. The last couple of times we had one invited guest to participate remotely (and preside over everybody else in the big video screen), but this time we opened it up so anybody, anywhere in the world could join us and participate in the updates and discussions through the web site (big thanks for Mike Berg for all the excellent work on the web site!). ...

I finally managed to get through the hotel wifi and upload the slides for this morning’s 360iDev talk: The Power Of In-App Purchases. Thanks everybody who attended for the great questions and feedback! Session description The common-sense approach to make money on the App Store used to be to do anything to get on the top charts. In-app purchases changed all of that. Good in-app purchases can make your app profitable without being anywhere on the charts, and are the best hope for the independent developer. Come to this session to learn why IAPs can be so effective and how to leverage them effectively: what makes a good IAP, how to increase your user involvement, how to present IAPs in an attractive way, what things attract users, and what things turn them away. We’ll go through lots of detailed real-world data from Flower Garden and other games with strong IAPs. ...

It’s no secret that I like a good conference. Actually, I’m sure I can find something to enjoy even at a so-so conference. Each field has it’s big, ultimate conference: For games it’s GDC, for graphics SIGGRAPH, and for iPhone development WWDC. Those big conferences have the big announcements, the big crowds, and the big players. But the smaller conferences always have something a unique to them that the big ones can’t compete against. ...

It’s that time of the year when all the games industry converges on San Francisco. Even though this is my 12th GDC (in a row, no less), and the conference has grown and matured a lot, it still feels as exciting as the first one. This year will GDC will host the first ever iPhone Summit on Tuesday and Wednesday. It’s great to see the iPhone getting that much recognition as a gaming platform. Definitely way more than last year’s presence at the conference. Both days are going to be packed with awesome sessions, and I will be giving a presentation on mixing OpenGL and UIKit on Tuesday at 11:15am. I’ll definitely be around throughout all the summit (except when I sneak out for a few minutes over to the Indie Summit which unfortunately happens at the same time). ...

A week ago, I sent out a quick tweet asking if anyone would be interested in doing an iPhone Game Jam at the 360iDev conference. The response was immediate and hugely positive, so, with the help of the organizers of 360iDev, we put together an informal iPhone Game Jam. The idea was to get together Tuesday evening, starting at around 7PM, and to code all night and have an iPhone game (or at least a prototype) done by morning. About 25 showed up, working on about a dozen projects. Participants were welcome to group into teams or work solo. There were no restrictions as far as themes or technology. The only rules were that you had to finish something by morning (no leaving something that was 5% of a game) and you had to start the game from scratch (no finishing a game you had started a while ago). ...

Here are the slides and the source code for my talk this afternoon at 360iDev in Denver. Thanks to everyone who came to the talk. I was surprised to see so much interest on this topic, so that was great. Session description: The iPhone has a very powerful engine under that shiny hood when it comes to floating-point computations. This is something that surprises a lot of programmers because by default, things can slow down a lot whenever any floating point numbers are involved. This session will explain the secrets to unlocking maximum performance for floating point calculations, from the mysteries of Thumb mode, to harnessing the full power of the forgotten vector floating point unit. Stay away from this session if he thought of reading or even (gasp!) writing assembly code scares you. ...

I just put up the slides for my talk this morning at GDC Austin: Squeezing Every Drop Of Performance Out Of The iPhone. Thanks for everyone who attended the session and for the great feedback so far. If you’re going to be in China next month, I’ll be giving a very similar talk at GDC China. Session description: This session will describe the iPhone performance optimization lessons learned through many hours of tuning. We’ll start with an overview of the performance analysis tools available on the iPhone SDK to help you narrow down your performance bottlenecks. Then we’ll cover the best way to set up your render loops, rendering best practices, how to deal with the limited memory, or even how to drop down to assembly to use the forgotten vector floating point unit. ...

For those of you still on the fence about attending my iPhone OpenGL class in Denver, you should sign up before this Sunday if you want to get the super-combo deal. Right now you get a total combined discount of over $300 if you sign up both for the OpenGL class and the 360iDev conference. If you’re only interested in the OpenGL class, the early-bird registration ends next Friday, September 4th. Obviously I’m biased when I say the class is going to be awesome (which it is), but I can also say with total honesty that 360iDev is an incredible conference. It’s very different from WWDC, but that’s what makes it so great: It has top-quality content and speakers, but it’s small and intimate, so you get to meet and hang out with all the other speakers and participants. It was at the first 360iDev conference back in March that I met Keith and Owen (among many other cool developers) in person for the first time and that’s how App Treasures was born. ...

I’m excited to announce the intensive, two-day class on OpenGL for the iPhone that I’ll be teaching. The class will be held September 26th-27th, in Denver, right before the 360iDev conference, and it’s part of the Mobile Orchard Workshops. The class is aimed at iPhone developers without previous OpenGL experience. It’s going to be very hands-on, and you’ll create both 2D and 3D applications during the weekend. You’ll learn all the basics: cameras, transforms, and how to draw meshes, but we’ll also cover some more advanced topics such as lighting, multitexturing, point sprites, and even render targets. Most importantly, you’ll walk away with a solid understanding of the basis, which will allow you to continue learning OpenGL and advanced computer graphics on your own from the docs, samples, or even browsing the API directly. ...

Things have been so busy ever since I got back from GDC that I never got a chance to upload the slides for my GDC presentation. So here they are. You can download the Keynote file directly from here, or view it online. The presentation went very well. The room was *completely* packed, with every seat taken and people standing along the walls. In retrospect I shouldn’t be surprised because it was the only iPhone presentation in the main GDC conference. Clearly there is a huge amount of interest in the platform. I’m already pushing to have a lot more iPhone content for next year, so you can all look forward to that. ...

Here are the slides for the 360iDev presentation I gave a few minutes ago. They’re in Keynote format. Thanks everybody for coming and all the questions at the end. It was lots of fun! Session description: This session will cover the experiences of a professional game developer, used to 200+ person teams, multi-million dollar budgets, and 3+ year schedules, who left all that behind to become a one-person indie company developing exclusively for the iPhone. It will explain how things are different and how some things are very much the same, and will show specific examples of graphics technology, development environment, and asset pipeline. I will be using my current iPhone project, Flower Garden, as an example. The audience will learn what the transition is like and what to expect going indie making games for the iPhone. ...

It seems like GDC was just the other day, but GDC 2009 is around the corner! And this year, I’m going to be giving a presentation titled iPhone Development: Exploring The New Frontier I’m sorry about reverting to the cliched format of having a colon in the presentation title. It was too hard to resist :-). I’ll be sharing my experiences transitioning from traditional AAA console game development, with teams of 100+ people, multi-million budgets, and several years of development, to indie iPhone development. There are a surprising amount of things that carry over from “big game development”, and quite a few that are totally different. I’ll go into what’s involved making games for the iPhone, and what game developers can expect when making the transition. ...

Spring was supposed to be the season of flowers, new leaves, and good weather returning. Here in San Diego we don’t get much of that, or rather, we get it all year around. So Spring can really sneak up on you, and before you realize it, it’s already gone. Spring also seems to be the season for game-development conferences and travel: just a few weeks apart we get Sony’s conference, Microsoft’s, and, of course, GDC. I’m not even going to count Dice and E3, also happening around the same time. ...
