As soon as I saw it I knew I was on to something and after 53 hours I want the devs to release into early access so I can try everything. I got so addicted that days were flying by I had to delete the demo.
Most shop simulators do not have an economy that flucuates and shifts like real life, Probably Stolen is not super indepth but it is one of the more complex shop sims I've played. Multiple starting roles, perks to make the game easier or harder, many different avenues on where to take your business a few example is dealing in weapons, drugs, food, rats... for food or something we all take for granted such as water.
In a game of selling products you wouldn't think there would be any use for a gun other than to sell but you can takeout your potential customers for specific reasons that you'll have to play to find out.
I found plenty of "OOOOH thats how it works" moments when I was trying new things and very few points where I felt stuck or shafted from bad game design.
The demo has quite a few spot the difference inspections on certain items where there are either counterfits, expired, broken or geniune.
Gun smithing and drug making is locked until release however I can see ways that the developers are going to create systems for them, I'm very excited.
If you haven't already tried it, I'd highly recommend trying it out while there is a demo over on Steam.
