I have every wish for success of this and every other business, but in the spirit of helping other impressionable developers, making a business is hard enough without making video games. How do I love games and hate games businesses, let me count the ways. User expectations are pegged by AAA games, whose budgets you cannot possibly match. Those AAA products set a price point at $DIRT_CHEAP. (Angry Birds costs what ?)…
What makes it hard is not the creation, so much as untangling your brain from all the nonsense about what makes a game "legitimate." If you go for legitimacy you'll fail off the bat because it is, as you say, a matter of competing with the big guys. But if you are adhering to lean principles throughout, you can get a game business going. It just may not be a "dream game," necessarily.
