What game can you play...

[V]

..over and over, beginning to end, and never get tired of?

Resident Evil 4 for me.  I fucking love this game and now that I have Wii edition, it makes it that much cooler.

Sonic The Hedgehog 2.

My favorite game as a little kid.

[V]

Oh god I've played that game so many times but I never beat it :'(
I never got past that one flying ship level after the Metropolis Zone


I've beat Sonic 3 at least a dozen times, probably about half of those with Sonic and Knuckles attached. Last time I did it was about a month ago, and the first time was when I was 7

All this talk of Sonic brings back old memories. I want my Genesis back. 

[LCK]

Super Mario World.

It was the first game I ever played as a child, and it was the first game I ever beat.
I've played and beat it so many times.

Me, my sister, and my brother had a habit of playing it almost every day. Over, and over, and over again.

Not Starcraft?

Actually no, I can't. I can for a long time but usually if a game lasts more then four hours I can only play that one game and won't start a new one. Never played single player missions though.

Well DOA4 if you count the multiplayer.

Darius Gaiden, Life Force, Super Mario World, Earthbound, and Sonic 3 and Knuckles.

Well......... All the games I have can have limited gameplay value per session, but if I could just get past all of the boss fights, it would be Megaman Legends.
