I'd recommend PunchOut! for the Wii, but not with the busted knee. Temptation is too powerful to get up and punch like mad. Call of Duty: World at War is great, especially if you have a good sized TV. Online play is contagious. I don't know how you feel about strategy games, but Fire Emblem is a good time. The Wii sports resort package should be awesome, but I haven't played it yet.
I'm simming through my second season with the Rams now. I managed to get Matthew Stafford, Aaron Curry, Michael Crabtree, and the 6th and 8th overall picks in the '10 draft without giving up any of my young stars except Donnie Avery, but that took me to a whopping 5 wins in season 2.
I knew Fallout 3 was deep but man, this is just insane. I've completed all of the mini quests and the main quest and yet I went back and I'm now trying to get everything. Like literally everything. And I'm still working on making my way to level 30. But I see no end in sight as far as everything goes. I don't feel like I'll ever be truly done.
