Which nations have contributed the most to gaming?

[digitalentourage]

I'm surprised how many people are ruling out PC gaming here... I know that as a method of profit it currently isn't as great as it could be, but I believe developers and publishers will begin to capitalize again on it in the future.. anyway, without further ado..

id software for Doom, pretty much the most revolutionary shooter ever created.
3d Realms for Duke Nukem.. the reason you have games like gears of war today.
Black Isle Studios: Kings of RPGs, no one has ever matched them.. along with
BioWare: Baldur's Gate?
Looking Glass Studios: System shock 2, ultima
Will Wright and co: Spore, The Sims
Blizzard Entertainment: Diablo, Starcraft, Warcraft, World of Warcraft
Valve
Bethesda
Maxis
Rockstar got their fame on PCs..
Remedy For Max Payne
Eidos for Deus Ex


In fact, for those who mention things like Tetris and jRPGs..

North Americans are responsible for tetris and japanese rpgs.
well, one north american.

Henk Rogers. He brough tetris to consoles (its not a japanese game) and he also created
"The Black Onyx" The very first Japanese RPG.
