Daggerfall is 100% free and better than most of the newer games

The company / corporation that owns rights to daggerfall decided to allow people to use it for free years after it was originally released for pay

People have spent years modifying it to remove bugs and improve gameplay, audio and graphics

It allows more choice than other single player games in the elder scrolls series from what I heard of

Consider playing old games and boycotting new stuff
