I've received a request to find out what the most popular / important Linux games are to you. For those that play any games on their Linux OS, please share the titles below. Once we have a nice list of games, we'll then set it up for a voting process.

While I don't normally play any games, I'll start by listing Enemy Territory: Quake Wars

Note: If you're playing games within WINE, just list WINE but the Windows game being run is not needed.
