I really like this game. I own this from DVDbox since this came out and steam. When I noticed that this was on GOG I instantly got it. All game play works but you cannot play coop or with random ppl.. I really think that half of the fun is with coop in this game.
I have few copies of this classic avp from the era when it was new. I have hard time to figure out why it needs galaxy client. This production decision does not allow it to be run on legacy systems which I personally use as much as possible. If you are using Windows 98 or XP get a used copy from some where else if you're going to pwn your friend(s) in lan =/
