That'll keep you busy.
Fallout 3 and NV plus both the Mass Effect games are great but you need to invest the time.
Is that the original Deus Ex you've listed?
Crysis/Warhead/2, Metro 2033, Just Cause 2... all a must for their eye candy.
Bioshock, Borderlands, Company of Heroes, Battlefield Bad Company 2, Starcraft 2, Batman AA... there are too many to name really, it's definitely worth going through the back catalogue of highly rated games. I spent my first couple of years of PC gaming doing this.
