I didn't get a 360 until last year, and so played a ridiculous amount of wii games. The Greatest ones I remember are Shattered Memories, Little King's Story, No More Heroes, and a bunch of first party games. Other than Oopora, this blog feels like the slightly hidden treasures of the wii, instead of the collection of weird stuff like domino hero(remember the QL?) or all the JRPG stuff like Sakura Wars.
Also Kawata Shoujo is a porn game(If I remember correctly).
