From the top of my head from the PS1 + PS2 era:
Crash Bandicoot 2
Crash Bandicoot 3
CTR
Crash Bash
Spyro 1, 2 and 3
Croc: Legend of the Gobbos
Killzone
GTA: 3, Vice City + San Andreas
Gameboy Colour games:
Pokemon Blue
Pokemon Silver
Xbox 360 games:
Assassin's Creed 1 + 2
Batman: Arkham Asylum
Beyond Good & Evil HD
Call of Duty 4: Modern Warfare
Crysis
King Kong
Lego Harry Potter 1+2
Lego Indiana Jones
Mass Effect 2
Minecraft
Naruto Ultimate Ninja Storm 2
Elder Scrolls 4: Oblivion
Spec Ops: The Line
When I was a kid I didn't have that many games so I just played the shit out of what I did have. Now I'm older I don't really go for completion unless I really like the game and it isn't an utter pain in the arsehole to 100%. Time is also an issue now.
