Older Elder Scrolls Freer
Bethesda have announced that their second Elder Scrolls game, Daggerfall, is now freeware. The classic RPG is notable for its enormity - being large and ambitious even by standards of the later games, even if it's visually clunky today. You can pick it up here, and it's under 150mb. You'll also need DOSBox to get it working, as it's quite literally that old. This announcement - made to celebrate fifteen years of the series - means that the first two Elder Scrolls games are both now free to play. You can pick up Arena at the same location.
