Thanks for the info, and the advise you gave me in Xfire chat. I might have a look into OpenTDD, sounds interesting, just don't pwn me on my first go. I'll do some gaming tonight I think. Got some stuff to learn first
Oh and as you guys can see, I still have a copy of Serious Sam 2 somewhere around here, it was a B'day present for my brother last year, and I enjoyed it myself as well. Playing that game in coop mode should be fun, right?
