normal on first playthrough. If its a really annoyingly challenging game (aka requires alot of grind or is just cheap) i just go and choose easy. If its a game i beat and love and i want more i go for Hard.

yes! Even the Wii one. Man I hate that second part -.-

I usually start on normal, but if it's a game I'm only interested in for the story I first check if the difficulty can be dropped down during play, if not I'll start it on easy.

I like it when you can change the difficulty, I started the last of us on normal and changed it to hard midway through. And I would have missed the best part of Bioshock infinite if I could not have changed it to easy to get past the annoying defense section.

Racing games I usually play on easy, competing with the moronic AI is not rewarding at all. I rather race myself perfecting each corner out in front of the pack. I'll go online for a challenge.

Easy or extreme, depends on the game. Normal is for noobs.

Medium.

Normal or Hard depending on the game.

Exactly big P

Usually Hard unless I just want to breeze through it.

Easy - 5%
Normal - 85%
Hard - 10%

I just made those percentages but they seem right.

Do you keep changing the difficulty in Skyrim?...imo, that game gets kinda easy really fast if I leave it on normal, but later not even the higher difficulties pose much of a challenge.
