Its benefit is the representation of complex situations of communal life, interconnections in society, and partial aspects of the economy (for example, the development of the railroad).
SIMgames have been said to be excellent hobbies for those who are for example allergic to animals, don't live near horses or just don't have the chance to be around them.
SIMgames are a great way to spend all the extra time or just to relax after a hard day.
But there are still farms in the internet who are happy to share their photos with SIM players who politely e-mail and ask for a permission and these farms are greatly appreciated amongst SIM players.
The remaining, overwhelming, 99% of horse simgame players sneak, steal, hot-link to images, feign ignorance, and are the first to defend their actions for doing so.
But, somehow, none of this seems to matter, and players of horse simgames typically take without permission, despite copyright notices, and hundreds and hundreds of equine images are being displayed, most of them hot-linked to other people's servers, leeching bandwidth 24 hours a day, 365 days a year.
They are not to be used for simgames, altered, reproduced, hosted on another server, or used in any other manner other than display on the web site that holds the actual copy rights to the image.
