Thanks for the info. My wife is dying for Mario Kart. I've been wondering how something like Resident Evil or Manhunt would be on the Wii.
I do have RE: The Umbrella Chronicles, and I think it's pretty good, but obviously very (much too) linear. It's like one of those arcade-type shooters, you know. Nice if you like that kind of games, and I do on occasion. Depends on who I'm playing with I suppose.
As for the others:
Excite Truck
Action smashed monster truck racing that's real fun, something to play with hairy men in wifebeaters while screaming WHÖÖÖÖ CHECKIDOUT! at every jump and drinking beer.
The Legend of Zelda - The Twilight Princess
Probably the best game for WII so far. If you like earlier Zelda games you'll love this. Possibly the second best one ever (after A Link to the Past), and if you've never played one you better fucking start.
Mario Kart Wii
Has some stupid shit (can't turn off computer opponents when you wanna duel your wife etc), is pretty much as Mario Kart usually is but with funner (is that a word?) steering
Okami
Like Zelda but, get this... You're a wolf!
Mario Party
Great when you're four people drinking beer and chatting and listening to heavy metal and need something laidback to do and don't wanna do advanced stuff like trivial pursuit or group sex
Super Mario Galaxy
GREAT GREAT GREAT game, MUST have. Also best while alone gaming I suppose, but it's so great and fun and innovative and well-made and smart that you NEED it.
Super Paper Mario.
Fun 2D platform RPG, takes fifty million years with all the dialogue, especially in the beginning but I enjoyed it.
Also, Guitar Hero is great but I've played it so very little and don't own it. Needs more heavy metal.
