Ah thanks for the feedback, friend.
Yeah... That's a great idea. I actually thought of implementing something like simple casino card game before (blackjack for instance), but back then I had no clue how to do it.
I'm currently testing more methods to improve the city. My goal is to have a somewhat big city with little mini games all over the map in different places, like the casino you mentioned, or playing chess in the park, etc. Would be so cool.
I'll let you know :v
