Well, 'bout a year or so ago, I picked up Operation Flashpoint. That's the most fun and excitement I've ever had in MP. Before then it was mainly Quake1 TF, Action Quake2, and Half-Life mods, like CS and AHL.
It's fairly easy to make missions for opflash, so I made a few and still haven't tired of the game after all this time. I tried BF1942, which has some cool points, but flying an airplane without a joystick sucks. Also, it's strange, but I'll get hit by a tank mortar shell or a rocket and live. Other times I'll get hit by a single bullet and die! Also, 9 times out of 10, it seems I'll just die for no reason. I won't hear a bullet or anything. I think there must be severe lag issues that cause it, although I haven't noticed any lag insofar as movement goes.
UT2K3 seems ok, but it's just too much like Quake3 for me to enjoy. Opflash offers exactly what I want--slower, more methodical team-based action.
I tried Ghost Recon as well, but the interface is really lousy. You have to hunt around for an icon just to tell what weapon you're carrying, and it feels like you're floating around with a reticle in the air.
If BF1942 gets better with the lag issues, then it might be worth picking up. Really, once you've played games with vehicles in them, it's awfully hard, at least for me, to go back to enjoying small, claustrophobic enclosed levels with no vehicles.
