Well, the old games are still around and still fun. Also, there's open-source games, which generally do multiplayer via LAN only. At my last LAN party, we were six people in a room without internet connection [1]. I brought a bunch of open-source games and ZIP archives of classic games with No-CD patches and put them on a plain HTTP server for distribution. We mostly played WC3 (with the original Dota map) and Widelands (a Settlers 2 clone), but everyone's favorite was Empty Epsilon (the OSS clone of Star Trek Bridge Simulator). [1] #Neuland :)
