I don't mind paying subscription fees, but I can't stand games that milk players for money with 'objects' you need to continually keep repurchasing for minor bonuses within the game.
I like color genetics but am not so hung up on it.
My only other little nit-picky thing, it's gotta have draft horses. There are lots of games I just can't get into because they don't have horses I like :P I know it's silly but it matters to me.
Thanks everyone! I'm happy to use someone's referral number too if you want me to when I join!
