Going back to the "Is farcry good?" debate.. I got bored of the single-player VERY soon.. But, this game in LAN, team Deathmatch is lovely. Add to that some custom maps, very lovely.
Hmm. I had a go of MP unpatched soon after release, the levels were uninspired and the FPS and collision detection were excrable. Doubtless the patches improved it (as the SP game was pretty much okay as was) but I never went back to find out.
