The "how much did you beat that game?" game

[Bop1996]

90% (I don't think it's possible to 100% it for real due to conversation choices and the like)

Super Metroid

 

[Mario4Ever]

I don't remember, so I'll say low to mid 60s, percentage-wise.

Fluidity

 

[Smashley]

Uh, does Superstar Ultra count? Because I 100% that game.

Yes, remakes count.

0%, never even heard of that one

Uncharted 2: Among Thieves

 

[Master Crash]

I've only beaten Uncharted 2 on Normal, never tried to beat it on hard, but I did get a few of the trophies, plus I did a lot of multiplayer stuff, so maybe somewhere around... 50-70%?

InFamous

 

[Smashley]

I haven't played the first InFamous, sadly.

Jak and Daxter

 

[Mario4Ever]

0% Never played it

Star Wars: The Force Unleashed

 

[Master Crash]

I suppose about 50%, beat it on the light side, but not the dark side.

How about InFamous 2?
