I'd like to, but I haven't in the past....
I'm trying to get through all of the Wii games I've got, currently although I'm not sure what "beating" Madden would entail...
I'm currently in the middle of Zack & Wiki, SMG, and Metroid Prime 3, fun debates most nights of which game to play, but I should be finishing Z&W within a month, I'm only a few hours from the end of Metroid, and SMG will take a bit more time but it's not a bad predicament to be in... I have plenty of PSone/PS2 games that I need to beat but just can't find the time. Most of them are the Square Final Fantasy anthology games which is held up mostly due to the lack of free time between work, and kids.
If I'm lucky I'll finish Z&W and Metroid before Smash Bros. comes out...
