I can be a little too Japan-focused and miss the European titles until they smack me upside of the head.
Due out shortly for the DS, Last King of Africa, a "complete reworking" of a PC adventure game by someone who, iirc, is better known for gorgeous environments than brilliant gameplay. There's some gameplay video here.
So, why do I feel underwhelmed? Do I only want to play anime games on my DS? Maybe I just want my DS games to be lightweight? Maybe it's because I know how very easily I give up on a game that isn't sufficiently well-matched to my DS controlstyle/playstyle? Maybe just because I have SO MANY GAMES that I already want to play that I can't deal with adding another to the stack? :)
