Or am I missing something? What is your purpose for making a game, and why don't you already know what you want to work on?
The main purpose (aside from the obvious enjoyment) is to see through the entire development cycle of a non-trivial project where I'm the only programmer on the team (both for learning purposes and because it's a major goal I set for myself since I graduated from school). I should probably have rephrased the last part to "...what the hell should I work on, taking into account points 1 and 2?" I think I know what I'd want to work on if I stopped worrying about #2 so much, though I'll admit it's been hard to get over that so I'm looking for some advice so I can make sure I take a step in the right direction.
