Funny you should ask, I just finished building one: https://startupsimulator.com

Let me know what you think - it hasn't had intensive play by a ton of users yet, so feedback is very welcome!

"Porn manager" - be a manager of porn studio, hire models, choose genres etc. The game becomes hard after the studio becomes big enough because of too many needs to be remembered. Sorry but the game is j2me only, requires something like Nokia S40 or Siemens *75. I don't even trying to find it, I have no compatible devices any more.

Other than being a list of all the details you need to pay attention to, wouldn't a simulation ultimately hinge on how well your product or service is received? Are you going to pretend your sales are terrific?

The infamous "beer distribution game" shows how difficult it is to simulate and manage an almost trivial supply chain. I would expect trying to simulate an entire startup would have so many variables that any simulation would only end up predicting real world performance purely by chance.
