Hmm, I dunno - when horses are competing at the world highest levels at 18+ years old, and they have a great career after that in lower levels, it's sad that HEE horses are considered done at similar ages
There seems to be a glitch with the seniors - it's been reported in Bugs. I like it for the realistic aspect - it made me so sad when 18/19/20 year olds were passing away. My friend's horse just passed away at 37 and he was active late into his 20s as an all around and trail horse. But I can understand that it's messing up the game mechanics people rely on.
