Linux gaming

Plenty of commercial Wintel games are available on Linux too. In many cases you need the Windows version for datafiles, then download the Linux executable for free. For these picks I'll focus on Free software.

• Circus Linux
• Frozen Bubble
• Koules
• NetHack and glHack
• Star Control 2
• Tux Racer with extra tracks
• A list of SDL-based games
