Meh, I had my Wii for a year or so before I hacked, and probably 1 1/2 to 2 years before I started pirating games for it.
I would probably have a longer attention span. When you pirate, you seem to lose interest in games quicker since you know there's always another game to play. When you don't, you realize you've got only your selection of games and not much cash to buy new ones (which is the case with me), and thus you play games to their fullest and replay them a few times as well. Hell, I played Twilight Princess through 4-5 times because there was nothing else to do, really.
I'd also be playing a lot of Mario Kart Wii and The Conduit, since they both have excellent online modes and can easily be those "100+ hour" games that the 360/PS3 has.
