Why do so many people want to get involved in the game development business? Most say "For the money" and "Because I love making games".
Ok, you want money - do business programming! You'll probably get more money, and you can actually fit a normal life between the working hours.
Oh, so you want to make games? Well, isn't it equally fun to do games in your sparetime? Join a open source project or gathering some friends to do it?
Conclusion... you'll get the money, AND you may choose when you want to work yourself to death with game development or not.
So why do you want to become a pro-game-dev-guy? Is it the I-wanna-be-a-rockstar-syndrome?
