I'm accepting towards all different kinds, but some I can never really get myself into is FNAF roleplays (and anything similar). Just not my cup of tea, I guess. I also can't get myself into human roleplays. Even though we are humans ourselves, and it would be easy because we know everything humans do/know how humans are, it's hard to imagine yourself as a human when you're using a canine or feline model (talking about in game here, not like a roleplay on a forum).
Besides that, I'm not much for wolf-speak. Nothing against it, I just prefer nothing too simple, but not overly detailed. Especially to the point where you're giving details to every little thing with words that are hard to comprehend.
