The chaps at GamesRadar have churned out a feature listing 30 PC games that are now legally free to download. There’s some really nice forgotten gems including three Amiga games from Factor 5 (R Type, BC Kid and Katakis) and Core’s Mario Kart-alike BC Racers. There’s also links to free downloads of Fallout, Grand Theft Auto, Metal Slug and Sam & Max Episode 4: Abe Lincoln Must Die.
Have a read of the full feature and see if anything takes your fancy.
