How did Halo 3 "push the envelope"? What, exactly, did it do that hadn't already been done? Same with Rock Band. I guess popularizing old tech is enough to grant you awards these days...
And frankly, though I haven't played the Orange Box - not my type of games, though I'm sure they are excelent - I can't see Portal, or any of the sequels, change anything decisive from an industry viewpoint, which seems to be what they were looking for in these other games.
Well, those are my complaints, anyway.
