If taking a game I already made and spending an hour on it to make it work on the OUYA, the rest is pure profit. Even if it's a a few hundred to a few thousand bucks
I wouldn't spend my time to make a game exclusive for the ouya though.
Which is why I changed my mind about making an Ouya exclusive after learning about the horrible sales.
However, I just may port my Galaxy Aggression game over to Ouya now, just need to buy the console now from Gamestop lol..
