F.E.A.R = crap
DOOM3 = crap
Quake 4 = worse than crap
Half Life 2 = crap (unless they make a good teamfortress mod for it)
Battlefield 2 = very nice
I'm a Quake fan for many years, since way back when Quake 1 online gaming started (requiem mod rocked), now it's so very crap they've simply revamped Quake 3 area (yawn).
FEAR,DOOM3,HALFLIFE2 all at the moment are so lame, they need some seriously good addons.
Battlefield 2 is very good, not the best online game I've played but at the moment seems to be the only one that stands out for me.
Oh and don't get me started on CounterStrike arrgghhhhhhh what a play ground of cheaters, there are now 22 bots and cheats (at least) available for that sh*te game. No, no BullDog(UK) deep breaths..................better
