Tetris (Gameboy) - It came with the system, but I played the crap out of this game because it is a brilliant and addictive game.
Super Mario Bros. - Not much to say about this. Pure classic and countless hours logged.
Final Fantasy III (SNES) - My personal favorite all-time video game. I have probably gone through it at least 6-8 times.
Guitar Hero 3 - I am a little embarrassed to admit how many hours I have logged on this game.
Skyrim - I have only gone through it once, but once is enough to put this game on my list.
Honorable mention: OoT, MW3, SMB3.
