what are peoples' choices for best PC multiplayer shooters. i've mainly played Rainbow six 3 and Star Wars Battlefronts, but i'm ready to move on. my friend keeps telling me to get Counterstrike. is the counterstrike version that comes with Halflife 2 compatible with the older versions?
what are the opinions on Unreal Tournament 2004? from what i have seen it looks good.
i want something that is fairly interactive (unlike Rainbow Six), that has stood the test of time and still has lots of people playing (unlike SW Battlefronts).
