I was reading this for the first time and I think it is a great idea :) But I was also wondering about if you were going to do a skill like Horse Handling? It could make it so that it takes the horse less time to get there, like you could get it to go faster and control it. You also could make it so it you need a certain horse handling skill level to buy/use a certain horse. Also how about a skill that could let you dig like areas underground, like tunnels and stuff, in certian marked areas,
