We tend to become very good at classifying stuff. It’s the easiest way to filter out things we assume we won’t like. Gamers are no different from everyone else. We all have some kind of mechanic or theme that we normally remove from our field of vision. Maybe you had a bad experience with it at some point, or maybe you just have a fundamental problem with it. For me, I’m not really a fan of stock games. It’s not so much that I don’t like them. (I consider Acquire to be one of the best games ever designed.) No, my real problem with stock games is that I’m terrible at them. Something about learning to manipulate investment eludes me, which is an unfortunate handicap to have in life.
