Yea, pretty much all of it. I like going on long, but creative quests. Not just go here, kill this, collect this, use it to do this-type quests. I'd want something where you have to solve a puzzle, where you have to think.
And big epic battles are fun, too.
Lots of adventure, and the ability to just freely wander the world performing side quests with little or nothing to do with the story.
And lots of room to upgrade a character with tons of skill options so that each character can be totally different than the other characters.
