Grargar: Ultimate Doom and
Doom II + Final Doom Both games received a new Unity-based version (see link below for more info), exclusively on Bethesda.net, some months ago. This wouldn't be so bad if the original versions weren't included, but they are. So, at the cost of 5 bucks for each game, you get access to both the original DOS and the new Unity versions. In addition, Final Doom is available as a free add-on for either game and No Rest for the Living (previously, a Doom 3 BFG-exclusive on PC) is available as a free add-on for Doom 2.

Note: Steam users who already own Quake will automatically receive the new enhanced version with a free download!
