I've owned a Wii and a ps3 since launch.
Wii - 4 games - All are first party (as 90% of the games I buy for Nintendo consoles are). Tomorrow No More Heroes will be added to this list, making it my first 3rd party Wii game. Zack & Wiki is also on my wish list, but I probably won't buy it until after SSBB hits.
Wii Sports
The Legend of Zelda: Twilight Princess
Super Mario Galaxy
Link's Crossbow Training
Virtual Console - 4 games, all NES and 1st party. LoZ: A Link to the Past will be my next purchase.
Super Mario Bros.
Super Mario Bros. 2
Super Mario Bros. 3
Kirby's Adventure
PS3 - 4 games (not including GTHD) - Three are 1st party, one is 2nd party. Ratchet & Clank is on my wish list, but I probably won't buy it until after MGS4 hits, if at all.
