I may try the demo, but I doubt I'll be that into it. I played a pirated version of BF 2142 (or whatever the "modern" version of it was) and found it to be nothing that special. Also, this game seems to have a checklist of things that would turn me OFF in a game:
No Single player (or at least no bots)
An overpowered sniper rifle
Very clearly defined spawn points
Few maps and fewer gametypes.
I suppose I should at least give it a chance though. After all, I ignored Team Fortress 2 for years because of its lack of single player and constantly changing structure, but when I finally tried it during a free weekend I quickly fell in love with it and it's reinvigorated my love for PC Gaming. But then again, TF2 isn't like most games, so I'm sure results will vary..
