What is the best PC horse game

Horseland.com is one of the oldest horse game websites and the fact that it has been around for so long means it has stood the test of time. It's free.

But as far as Horses Games for the PC is concerned, I had to ask my Horse Mad daughter and she said she likes:

Planet Horse - because it has brilliant graphics

Riding Academy 1 & 2 because she felt she was able to grow up alongside the heroine.
