It's completly useless to buy this game on GOG.com, since it's not actually DRM free if you want to play this with friends (what is the whole point of buying games here). I really wish back the time when you and your friend just brought a CD/DVD to test a game together. Now, everybody has to buy a copy of the game, just to find out if it's worth it or not. I think I'll start getting cracked copies again.
