I only played the single player mission so far but I think it's a pretty good game. The graphics are good enough for me and I experienced no sysdumps or frame rate lag. The sounds are good but the AI is still not very smart. I don't care much for AI though. I've become a little more excited about this game after playing the demo.
Good:
Graphics are decent and colors are vibrant (I’m not picky)
Fast paced game play, like in the old days
Decent weapon selection
Nice menus with crisp graphics
Bad:
Shotgun is overpowered (Seems this is the case in most games)
AI is about the level of DFLW and can still shoot through buildings
Map and objective system needs work (won’t matter online)
At some points all objects disappeared for a brief second
I took a ton of screen shots, which can be viewed here:

As it stands I would probably buy this. Thinking about getting a gold membership to play the demo online.
