I have no idea how many hours of Wii I've clocked in but I've had it since launch and played in pretty frequently at least for the first year or so until I kinda shifted over more to my 360. My very vague ballpark guess though would be roughly 1000 hours, with the majority of the time consisting of Mario Kart Wii and Smash Bros, both rediculously addictive.
I really gotta get back to playing Mario Kart, I miss it.. The online was actually really solid and a lot of fun now that I think about it, and I got pretty damn good for awhile. I was pretty near the top of the ranks in that retro Boo level. I wish they'd have an actual leaderboard that ranked each player by number for each level, instead of showing you vaguely where you fall on a graph..
