Guilty Gear: Accent Core is on the Wii, Tusanoku vs Capcom is importable for those outside of Japan.
I have one too many horror games, RE:UC is scarier than the ones I have, I don't even remember their names, they sucked that bad.
Racing... Cruisn... never mind - wasn't Ferrari Challenge released on the Wii?
The only thing I'm upset about though is the lack of Devil May Cry on my Wii, I enjoyed that game - granted No More Heroes was better in most regards but Devil May Cry still had it's own style, it's a bloody shame Capcom was more interested in Chop til you drop.
At this point though, I've been waiting for Gravity to make a move on the Wii platform, they have been in position to do it since spring 2007, I honestly wouldn't be too shocked about it, right now I believe they are in a race to the finish line with Nexxon (I believe thats how it's spelling goes) to provide a genre that hasn't appear on the Wii platform yet.
However if I'm correct Nexxon is more in a position due to relations with Nintendo to go 2nd party, if they do this their games may stay on DS for a while, which means no Gravity on Wii.
