Well that's all I've seen so far, but the even the fact they have something to show after all these years and mods turned retail games is a major accomplishment.
Speaking of id software, I'm still miffed over Doom 3 being awarded Game of the Show at last year's E3. If it weren't for the leaked demo post-E3, we'd know squat about the game (we barely know more than that right now) besides the fact that is has nice graphics. Oh, joy.
For a game to be a viable GOTS contender, I think it should be in a playable form for the public attendees. Also, I think once a game has received a GOTS award, it should be automatically ineligible for subsequent GOTS awards, regardless if it receives multiple showings over a number of E3's due to delays and various prolonged development periods.
