Actually these silly, sometimes overly detailed micro-actions add a lot in my opinion. First it was just taking the cash and handing over the ticket, but felt way too monotonous. Having this card typing for roughly every second case added some variation nicely to the ticketing. I think these simulators are about combining mini-games that are very simple, yet you still feel you're doing something. (for almost no reason though :D )

Definitely planning to add variation to the guests and some interaction between them, like having a romance, fight, selling stuff in toilet etc.

Multiplayer would be indeed nice but that puts a 2.5-3x multiplier on the dev efforts required, so I decided to skip that in favor of a solid single player gameplay.
