Samba De Amigo: a supposely "casual" game. It is certainly not "casuals" who managed to get the only few copies of the Dreamcast version shipped in Europe. Only 500 games were shipped here in France, and unfortunately I didn't manage to get one (I wasn't aware of the release date, and was too late to get it). So, I'm very excited about a new version being released on the Wii and the last preview suggest the controls work very well.
Tales of Symphonia: Dawn of the New World: I really enjoyed the first Tales of Symphonia, played it 3 times to complete all the item/monster/recipe/... lists.
Mega Man 9: Mega Man is a well-known series I've never played. I love the idea of going retro for this new one. It also makes me want to get Mega Man and Mega Man 2 on the VC.
Dead Rising: Basically the only game (along with Metal Gear Solid 4) that interests me currently out on the HD consoles. I'm a fan of zombies, the original Dawn of the Dead film,...
Bomberman: best multiplayer game ever. I didn't really care for the console versions from the 2 last generations, and I'm hoping this one turns out being as good as the ones I loved on SNES.
Runners up :
Animal Crossing: City Folk: I've never played an Animal Crossing game before, and since it seems to be a major franchise I feel like I'm missing out.
Wii Sports Resort: Wii Sport was great fun. I'm hoping the sequel will be as good/better. And the 1:1 add-on seems quite interesting.
Wario Land: The Shake Dimension: I love 2D plateforming and can't wait to play a new, recent 2D plateformer. I didn't get Wario Land 2-3-4 and should probably get and play them beforehand (if I find the time)
de Blob: looks nice. Although the game is probably very different, the concept kinda reminds of Jet Set Radio.
Pikmin: I really loved Pikmin on the Gamecube, especially the first game.
Project Zero IV (Fatal Frame IV): I'm fond of survivor horror games, so I'm interested in this. I should try to get the first three games too, but since the stories are not related, I can wait for number IV and see if I like it.
