SMB3, SM64, SSBB, Sonic 3 and Knuckles, Star Fox 64

In my opinion nothing should ever get a perfect score because that implies that said thing is perfect.  Last time I checked there is nothing that is perfect.

I have many games that i would rate a 10 those are either ones that once i get i cant stop playing for hours literally at leasy 12 hours straight or a game i keep coming back to time and time again.

I would if I felt a game had everything. But, to date I feel that games lack still haven't crossed the graphics threshold, still don't allow you to interact with absolutely everything, still games do not all run at 60 FPS, have not perfected AI, and lack really true natural motion with people.

I will 10 probably within the next two or three generations.

Ninja Gaiden Black for Xbox 10!!

Portal is one I'd 10, with a high five too.

Of course.

Lost Odyessey
Mario Galaxy
Mario strikers
Mass Effect
Halo 3
Super Empire strikes back
Super Mario World
Super Mario 64

A 10 for me is a game I never get bored for one thing.
And how it hits me emotionally. AlsoI never rate multiplayer in my rating thats a different thing. Because your experience changes each time yoou play.

I could ad more to the list, but cant be arsed.
