I'd like to do 100%, but after going through one route (usually the girl I like the most, though I'll also do the main heroine if it's a different person) I know most of the story, and I find it annoying knowing things the characters haven't found out yet, and I'm not really the type to skip through everything to the CGs, since I do like to know the little bits of story that are different. There are a few eroges that I do play 100% through though, or close enough, if they have a good replayable story.
