Mario, surprisingly and yet unsurprisingly. I've never even considered myself a Mario fan until I realized how many games are truly "Mario" games. Mainline 3D Mario for single player. Super Smash Bros. for fighter. Mario Kart for racer. Mario & Luigi for RPG. Mario Strikers/Mario Tennis for sports. Super Mario 3D Land for Party. New Super Mario Bros. for 2D side scrolling.

And I'm crossing my fingers for the eventual Super Mario Paintball to satisfy my shooter needs.

Then I'd read a book/watch a movie when I want a good story.

*heavy breathing*

Just... 10 hours for me !!!

despite the frustrations, I would probably go with fifa.
I know it will be made forever and there will be 1 every year =P

Assuming I can use mods then Elder Scrolls. Each game is transformed by mods and DLC to the point of completely transforming each game until the next one arrives.

Even though it's not my favorite franchise, I would choose 3D mario. Those games feel basically new to me when I play them a couple years after.

Zelda

LittleBigPlanet

My mind just exploded.

PC: Sid Meier's Civilization

Console/Handheld: The Legend of Zelda

Metroid!
