Ooh, I'll play.
Final Profit: A Shop RPG is an RPG about a deposed elf queen who opens a humble shop and slowly advances through the ranks of the Bureau of Business with the eventual goal of defeating Capitalism from within. It's unique. It has some incremental game like mechanics, and can get a little repetitive in the mid-game, but it has a surprisingly compelling story and a lot of unfolding mechanics that keep it interesting all the way through.
Roughly a 30 hour playthrough with many endings, NG+ and some optional challenge modes that remove or change some of the most obvious strategies for advancement, so if you finish it and still want more, you can play through again with a somewhat different experience.
I'm supporting the restaurant by eating there, and paying menu prices for food. If they need me to pay more, they can raise their menu prices. I'm not going to guess how much things actually cost.
