Personally, I cant wait for Bomberman Live!, Ikaruga, and Quake 3: Arena (if it comes)

Bravo!! Very nice list!!

Is Ikaruga official? Because it’s ridiculously hard to find that for GameCube….

Actually I think its Band of Bugs this Wednesday.

It is.

is it worth my while buying these games again as I already own them on defunct systems and use emulators to run the games on my PC through my HD TV?  They look awesome with OPENGL or Directx filters.

It didn’t see it on the rumored list, but I think Spyglass Board Games is supposed to appear @July or so.

- Toy Soldiers is a tower defense game, although none of its promotional materials contain the words “tower” or “defense.” This was probably a calculated decision, as the tower defense genre is overcrowded with copycat clones and mediocre me-toos. But for classification purposes, Toy Soldiers is tower defense. It’s also one of the good tower defense games, so fans of the genre will want to check it out.
