This is tough as it has changed a LOT over the years. I remember back in the day FFVII was like the greatest thing EVER! Not anymore with all the awesome games now.
Right now it's probably:
1. The Last of Us (PS3/PS4)
2. Shadow of the Colossus (PS2/PS4)
3. Silent Hill 2 (PS2)
4. Uncharted 2 & 4 - can't decide
5. God of War (PS4 - I gotta wait until I finish this to know for sure but DAMN!!)
6. Metal Gear Solid 3: Snake Eater (PS3)
7. Need for Speed: Hot Pursuit (PS3)
8. Tekken (3, 5 & 7)
9. Final Fantasy VII (PS1)
10. ICO (PS3)
Honourable mentions: SSX (PS3), Ridge Racer(s), FFX, FFVIII, Zelda: Ocarina of Time, Streets of Rage 1&2 (Genesis), Ninja Gaiden 1&2 (NES), Castlevania: Symphony of the Night, WipEout (all of them!), Resident Evil 2, SUper Mario Bros. 3, GTAV,
