2007 1UP Award Winners

1UP has revealed the "Game of the Year" picks as made by their network readers, with the "RPG of the Year" being Mass Effect.
Mass Effect (PC, 360) Microsoft/BioWare

Give people a galaxy and they'll want the universe. While BioWare didn't give role-players a game quite as big as the infinite cosmos, Mass Effect still provided a lot of planets to visit, people to talk to and stories to unravel. Even action-minded players could get into it thanks to the gunplay-centric combat.
The GotY is Halo 3.
