A good list of games that you should get now.
No More Heroes
Super Mario Galaxy
House of the Dead Overkill
Zelda
Metriod
Smash Bros.
Punch Out.
Resident Evil 4
MadWorld
Games coming out that you should get.
The Conduit.
Red Steel 2.

Few games that are just not in my genre.
Tiger Woods
Virtual Tennis

Wii has enough games now to keep you busy :P Looking at the lineup of rest of this year should be a good year to be a Wii owner.
