A lot of these online horse games involve forums, with intricate, detailed set-ups for fictitious auctions, sales, banks, etc. But really, my two interests are just breeding and racing my own virtual horses. I'm not interested in training strategies, selecting jockeys, keeping track of vet and farrier bills, and all of that. I don't want a game with forums because that takes time to participate in. You have to read all of the darned forums to have a hope of keeping current with the game. Just reading my LJ friends list is rather time-consuming.
I don't want to have to keep up with forums. That is why I have left quite a few activities I used to enjoy, because it just got to be too much and too time-consuming.
Bottom line--I want to write books. Time-consuming horse games have no place in that.
