Not good!

This game has a lot of issues before it can be deemed a good game.
The points system is completely off.
The diamonds are a rip off. They take diamonds and dont deliver them.
"Friends" get to use your horses to advance their stable! This one is ridiculous as its not fair that one has to work to get rare horses while another can just be lazy and steal horses to breed with! Makes being friends with anyone on this game a total joke.
Cost of breeding is way too high.
When mucking out stalls or grooming the cost is way to high compared to the points received (or the lack of points I should say as you get nothing for these actions).
Until these issues are fixed this game will be nothing more than a frustration, unless youre stupid and spend real money on this crap.
