For the 10th anniversary of the Elder Scrolls series, Arena has been released as a free download! Though there’s a link to the DOSBox emulator so you can run this old DOS game in your Windows, you’ll probably also want to download D-Fend, a front-end for DOSBox that’ll make things easier.
And, seeing as though I’m posting all these links, why not check out my old GameSpy Hall of Fame writeup for the Elder Scrolls series?
