I don't have much in way of expectations for characters going into games. If a character is interesting, fun, pretty (I am that shallow), or doesn't have any traits that just annoy the smurf out of me I either like them or feel indifferent towards them. When I analyze characters for my reviews (albeit this is in the case of movies) I find myself noticing a lack of depth for a lot of them. There just isn't much to talk about with a lot of characters I've seen and they can be summed up in one paragraph. So, if a character happens to be complicated and someone you could write an essay about, I prefer it.

Basically, I like characters I didn't even know I would like until they're created.
