Do you feel the need to %100 every game?

I do try and 100% the games I play. By that, I mean finding and completing all the content available in the game. Occasionally I will come across something that is too hard, and I will eventually give up on it. An example of that would be Super Smash Bros. Brawl. I never opened all the doors on that challenge board thing. I did the vast majority of them, but the last 10 or 20 were hard enough that I didn't feel bad giving up on those.

The games I play generally do not have achievements or trophies, so I don't care about that.
