first fps i tried involved Delta Force - Land Warrior in which i either got kicked for shooting people (namely the only people in the game, the team that ran the server, who were shooting at me), or found a server where a team had every spawn point covered with a rocket launcher
second (and last!) fps encounter was UT:Game Of The Year Edition (it's correct title, i was more interested by the fact it ran on Linux from the same CD, which i thought was something i had to try, but gave the disc back before i could) - which year i'm not entirely sure, but i think it's either 1999 or 2001, which was lent to me by a friend, however what i got was a bad copy that my friends friends boyfriends mate got, and i couldn't be bothered to find out where he got it - probably "Dodgy Daves Discount Deals"!, however it played online fine (being so old it was designed for dial up, so even my ailing wireless broadband with the packet loss from hell could cope), and i had quite a bit of fun with it, mainly because i am to meek to do anything but be a sniper, which actually made me quite good at getting some "frags", although after trying "Morpheus" - a tiny map (no bigger than four roofs, a layer underneath, and a road a little way down) which is set in space, and thus has reduced gravity and about the most destructive weapons (a great combo btw, you look round and see nothing but a continuous luminance of muzzle flashes flying through the air while a circling player reigns rockets into the floating dreadnought!) i got completely thrashed as you could almost fly raining rockets, weird spinning discs of death and bullets down on your enemy like some demented god!
