Same for me. I'm 14. I was 13 when I started TSO. I may not have liked it but when exploring EA I found Earth & Beyond. That was fun and I would still be playing it if it wasn't dieing.
What is with horses? This idea was also suggested on the runescape boards on runescape.com. I see no use for them. As a means of transportation? On TSO you instantaly go where you want to go.
