Great choices there! the Unreal Tournament and Morrowind soundtracks have been stuck in my head for a long time now. UT in particular -- I listen to the full album about once a week while I'm working.

I never played Deus Ex when it came out, so I don't have the nostalgic attachment for that one, but I just discovered this a few days ago: https://alexanderbrandon.bandcamp.com/album/conspiravision-deus-ex-remixed. I bought it and am giving it a full listen today. Highly recommended; probably that much better if you're a fan of the game.
