If your making a game, don't make your goal about money, that's how you mess up. Because if your goal is about money, then your focus is to get your game out there more quickly, making it sloppy. Your goal for this game instead should about improving your skills and learning new things. And then, if your game blows up, money becomes a factor. But for right, keep your goal about improving the game in any way possible and improving your skills, not about finishing the game and getting money for it.
