Are there any good horse games besides Howrse?

I liked Howrse but I don't like how you can't customize the horse or anything. I was wondering if there was a free game like the Pirates of the Caribbean online where you design your character and stuff? I don't care if the horse game lets you be the horse or makes you take care of it but something like that because I decided Howrse is just too slow waiting all day and stuff. Please and thank you|||Horse Racing Games
