Elder Scrolls II: Daggerfall today celebrates its 15 year anniversary and to help celebrate you can download a free version of the full game.
Daggerfall, like the other games in the Elder Scrolls series, takes place on the fictional continent of Tamriel. In Daggerfall, the player may travel within the High Rock and Hammerfell provinces of Tamriel. A wide range of formidable enemies, the strongest of which are the Daedra, make the journey through these realms difficult.
It’s also pretty awesome for free.
The game can be downloaded here.
