Now i'm not denying how good it looks, frankly it's mind blowing but what i am concerned about is the gameplay. Epic is a very talented developer that can make great games but its mindset if firmly fixed in that of multiplayer games. If you look at Epic's track record their sinlge player games fall short of their mulitplayer Tournament games, observe:
Unreal (Pc) - 8.4, Unreal 2 The Awakening (Pc) - 7.9, Unreal 2 The Awakening (Xbox) - 6.1, Unreal 2 The Awakening Special Edition (Pc) 7.9
Unreal Tournament (Pc) - 9.5, Unreal Tournament (PS2) - 8.2, Unreal Tournament (DC) - 9.4, Unreal Tournament 2003 (PC) - 8.8, Unreal Championship (xbox) - 8.5, Unreal Championship 2 The liandri Conflict (Xbox) - 9.0, Unreal Tournament 2004 (PC) - 9.4
As we can see Epic can achive good single player games and Great multiplayer games. So I predict that GOW will be a game that looks like a great game but will merely play like a good one, Epic is stuck in a recurring mindset of churning out fantastic games built for online.
