Re: MW2 server possibilities
The server would need a graphics card good enough to run the game, and a lot of servers either don't have them, or have a very low end one.
What you mean is, have someone set up a private match on a dedicated machine, with the FULL game installed. Too expensive and impractical unfortunately
I am sure some boffin will make the dedi server files though, there must be someone out there with the know-how. It is cod4 under all that new stuff after all.
Or just Mod COD4 with the new weapons/maps? MW2 is basically cod4 + peoples code4 mods anyway.
