My list is almost endless, but I will put the games I like the most
CHESS -)))))
Dune
C&C 1 and C&C Tiberium Wars
Red Alert
Duke Nukem 1
Blood
Shadow Warrior
Civilization (1,3,4,V)
Warcraft (not WOW)
Half Life (2)
Crysis Warhead (Crysis 2 is shite compared to the 1st Crysis, EA ruined everything with their Console support, thanks to Xbox and PS3 - they fecked every decent game with their performance limitaions of 2006)
GRID RaceDriver
The Elder Scrolls Series
GTA Vice City
Mass Effect Trilogy - the 1st one was the best
Splinter Cell series
Larry 7
Full Throttle
Best Multiplayer games
ETQW - one of the best, still play it online
BF3 - decent only if you have an admin on the server to ban the cheaters and balance the teams
Counter Strike 1.5
Mortal Combat
Battletoads
Most likely I missed a lot of good games. I've been playing games since 1989, it's hard to remember all of them -))))
It's a shame we don't have a lot of good games these days -(((
Look at this game for example, for today standards most of you will say that it's an utter shite, but hey it was written for 7.61 Mhz CPU with 64Kb of RAM and 64Kb of VideoRAM and the maximum game size was 16Mb!!!

For everyone who is looking for challenge games, try to complete Larry 7 without any help, the game is a real fun!
