Oh I have so many, in order of popping into memory (I am incapable of making top 5 or 10, even a top 20 I have been gaming far to long for that).
Top have to be:
S.T.A.L.K.E.R. SoC
S.T.A.L.K.E.R. Clear Sky
F.E.A.R. (even Perseus Mandate, looking forward to Origin)
Call of Duty (all but 3)
Deus Ex
Crysis and Crysis: Warhead
Morrowwind, Oblivion
Harvester (extremely violent 2D point and click adventure, picked off the shelves just as they came to ban it)
Blood and Blood2
Duke3d
Black & White (even 2 I guess, EVIL ROCKS)
The Witcher
No One Lives Forever 1 and 2 (hoping and praying for 3 someday)
Aliens vs Predator 1 and 2 + add ons (Prefer two cause it actually had a story)
Shadow Warrior ("You wanna wash Wang? Or Watch Wang wash wang")
Serious Sam
Rune (the viking game from Human Head)
Requiem: Avenging Angel (first game with bullet time, before there was a Matrix)
All Battlefield games
BioShock
Dead Space
Tie Fighter
X-Wing
X-Wing Alliance
Left 4 Dead

Terminator 2099
Anyway I could go on and on I will forgo the Atari and Coleco era for the sake of space. lol
Games I hate, the list is short.
Far Cry 2 for dieing of incurable consolitis
Doom 3 for repeating the same scares over and over and sucking bad
Far Cry for every level after the Doom 3 ripoff Trigen show up
Kind of hated Mass Effect as well... Got bored fast
Terminator Rampage for the key stuck in the room with no doors (**** you Bethesda for never fixing it)
