If you didn't get all up on the Good Old Games beta, you (and the rest of the public) now have a crack at the open beta of the service, which lets you purchase classic, DRM-free PC games for $5.99 or $9.99 a piece.
In addition to previously announced Codemasters and Interplay titles, GoG is now sporting games from Strategy First (e.g. Jagged Alliance) and Pluto 13 (Gothic). Oh, and if you need to play a little catch up with the Fallout series before the third game drops, you can get the pair of predecessors for $12 on GoG.com.
