More FPS fun: There's this awesome looking mod for Battlefield 2142 called First Strike. It looks way more fun than Battlefront, but Battlefront wasn't bad either IMO.
I play First Strike each Weekend, and it is indeed more fun than Battlefront
If you want to play Multiplayer. Battlefront I & II has some nice Singleplayer Missions, but lacks the kind of Teamwork Tools that Battlefield 2142 has.
