Someone should make an OpenGL ES 3.0 engine that works on all of these platforms by default: Win/Mac/Linux/Android/iOS/WebGL (or Native Client, at least). I think it would be very popular in a year or two. I've been enjoying indie "mobile" games for PC's a lot more than AAA type games lately, because they are easy to get into and fun. They seem to focus more on game-play than "regular" PC game developers do.
