I had an idea yesterday, while i was drinking...
I think that the 1st place winners of a horse race should recieve an item upon winning.
And this item should be a trophy or one of those decorative flower reefs they give race winners in real life.
But i think a trophy would suffice.
And the trophy would be a treasure item.
And if you wanted to go a little bit further.. instead of it being a generic treasure item could make it a unique/personal treasure item by having the players name on the trophy (for the picture of the item), just lke the icon you see when you win a race.
And also upon winning first place i think the winner should also recieve 1 food + 1 Medicine for their efforts.
Could make it a certain type of food/medicine or random generation.
I think this would encourage more ppl to start a breedery/training ground.
Make them strive to breed/train better horses and participate in races.
