LAN games

Well, me + some friends would like to make a lan party, y'know, just to play games and stuff...the problem is...we don't really like each other's games...

for instance, 4 of us are totally RTS addicts, the rest, they just simply cant think a little bit more than "shoot, reload", and, well, we RTS addicts do like FPS too ^^

But...which FPS...

Half of us like UT2K4, the rest, they simply HATE it...why? cuz they loooove counter strike..in fact, one of my friends came over to my house and well, he does play really good @ counter, so I said to him if he would like to try UT and he did...10 minutes later "this blows...counter is A LOT better than this, this game is just about killing everything that moves...counter is more about having a good shooting technique...", probably he said taht cuz he got his ar53 wiped 22-3 in 5 minutes with 4 bots....but anyways...we simply can't agree on a single game to play... (the rest of my friends saw a little bit of unreal with some videos and they thought the same "too fast"...heh, and they were :| with a nexuiz video...triple frag in 21 seconds xD)

I aslo suggested battlefield 2142 BUT...except from 3 (myself included), they are all running on-board video....so I think battlefield is off the charts...

So, after all of this nonsense..."whats the point?" simple do you have any suggestion on what game can we all play that satisfy everybody?

The game doesn't have to be the latest nor the hottest out there, just one that isnt as counter but neither "as fast" as UT, also, nothing like Medal of Honor nor battlefield 1942, more futuristic would be nice(most of us like sci fi tech guns xD, other games have too "standard" weaponry), and well, not too much demanding on the video side (but also nothing that is a giant pixel with a little pixel as its gun)

Any help would be appreciated
