Horse games for Wii, Nintendo Ds, or PC?

I'm trying to find some good horse games. I have a Wii, DS, and PC. I'm asking this in the horse section- because I figured horse people will probably know a lot more horse games.



-I haven't really had any ones with dressage, do you know of any out there?



-I have a really really really hard time finding free trials for the PC games. Are there any websites or would I just have to buy the game?



-Please nothing like Barbie.Horse games for Wii, Nintendo Ds, or PC?
