I used to play this game when I was in middle school, It was different you could look at the breeding charts and figure out what horses you needed to breed a special horse or just one that you really liked for example I loved the Mustangs and Curly's the most. 

I have always had a love for horses and now I have to many to could on 2 hands in real life! 

I have somehow managed to come back to the game!
