I don't think I use the horses much outside a few stories, it depends on how they are implemented with other worlds. I can however definitely see this world becoming a favourite of mine, and in that case I will use them a lot more.
Other stuff I love the looks of the item and clothes so those I will get a lot of use out of.
And OMG that lamb and goat, they are so CUTE they will definitely make their way into most games.
