even if you love horses this can hardly be called a game...
The second thing is to put some accessories on your horse.
The last one is taking care of your horse: eat, drink, brush, pet etc.
In 5 min you see all about this and there will be nothing more to do.
If you want a better game, try Time to Ride: Saddles and Stables, it's at least twice as good than this one.
I'm still waiting for an interesting game with horses, because all until now it looks like they tried to be realistic but in fact were stupid and boring...
