The media have covered to death both sides of the coin: The stories of developers striking it big, and how the great majority of indies don’t recoup their costs. A few days ago, Markus looked at indie iPhone development and how there is a middle-ground group of developers that are able to make make a living at it without going broke but without getting that big hit. Let’s call them the developer’s middle class. Markus suggested that about 20% of developers fall in that middle class, but my gut feeling, when it comes to iPhones and games, is that it’s more like 5-10%. But it’s just a made up number based on personal observation anyway. It would be very interesting to conduct some sort of survey (or analyze the App Store data), but I fear the results would get muddled up due to the differences between full time indies, hobbyists, and big companies. ...

One of the items in my ever-growing list of things to write about, is the rendering techniques I used in Flower Garden. In the end, it would make for a post with lots of pretty pictures, but there’s nothing particularly ground-breaking. After all, it’s all limited to OpenGL ES 1.1 on the iPhone, which means only two texture units and a two-stage texture combiner. As a result, more interesting ideas keep bubbling up to the top of the list and the poor rendering idea keeps getting passed over. ...

You’re not alone, I was also doing prototyping wrong until a few years ago. There are probably many different ways of prototyping games correctly, and maybe your way works great for you. In that case, a more accurate title for this post could have been “Prototyping: I Was Doing It Wrong”. A good game prototype is something fast/cheap that allows you to answer a specific question about your game. The key points there are fast/cheap and specific question. It’s not a level of a game, it’s not a “vertical slice”, and it’s certainly not an engine for the game. ...

In-game point bundles are nothing new. Even before the time of in-app purchases, Zynga was famous for releasing “points” apps to increase your game reputation or other stats. The fact that they released not just one way of getting points, but many different apps at different price points, was something I dismissed as a marketing tactic to try to get noticed on the charts. Fast-forward to now, and as more companies are jumping into the bandwagon of games that need “points” to make progress, we’re still bundles. Again, I chucked that up to legacy reasons and doing what worked with the standalone apps. ...

I’ve long been a fan of minimal game runtimes. Anything that can be done offline or in a separate tool, should be out of the runtime. That leaves the game architecture and code very lean and simple. One of the things you potentially give up by keeping the game runtime to a minimum is an editor built in the game itself. But that’s one of those things that sounds a lot better than it really is. From a technical point of view, having an editor in the game usually complicates the code a huge amount. All of a sudden you need to deal with objects being created and destroyed randomly (instead of through clearly defined events in the game), and you have to deal with all sorts of crazy inputs and configurations. ...

Anybody who worked with me or saw any of my code, would know right away why they call me the Const Nazi. That’s because in my coding style, I make use of the keyword const everywhere. But instead of going on about how const is so great, I’m going to let Hitler tell us how he really feels about it. No Flash? Try the QuickTime video version. Let me get one thing out of the way to stop all the trigger-happy, const-bashing, would-be-commenters: const doesn’t make any guarantees that values don’t change. ...

It has been two months since the last “numbers post”. It covered the Valentine’s Day promotion, spike in sales, and subsequent settling out at a very nice level. Here’s a recap of what things looked like at the beginning of May (revenue was about $1500 per week): The Plan Mother’s Day happens at the beginning of May (in the US and Canada anyway, I’m afraid I was too busy in April and I missed Mother’s Day in a lot of European countries). I figured it would be the perfect time to do another push. ...

This is my first entry into #iDevBlogADay. It all started very innocently with a suggestion from Miguel, but the ball got rolling pretty quickly. The idea is to have one independent iPhone game developer write a blog entry each day of the week. At first we thought we would be hard-pressed to get 7 developers, but it’s starting to seem we might have multiples per day! Check out the new sidebar with all the #iDevBlogADay blogs. We’re also putting together a common RSS feed if you want to subscribe to that instead. ...
