I had an Equus Sims stable a couple years ago and fell inactive. I've returned now with a new start, but I noticed I'd been keeping track of my old horses' ESI and I can't remember what that could be or how it's increased?
Unfortunately the ESI was given up after the change to 2.5 so nowadays the only factor influencing the horse's performance in R shows is the pedigree bonus.
Ohh okay. Thank you!
