A couple more casino games if possible - ideally poker (Heads up 1 v 1, or 6 max) and roulette.

Also earning rep from winning at casinos. Perhaps earning X amount of rep when meeting a specific hurdle. 

You could change the amount  gained depending on player levels, for example a level 1 might gain 50 rep for winning  X amount while a level 25 would gain X amount (to make the levelling rep requirement system work). This would also help incentivise players to use the casino more.

More than happy to help with anything poker rule related.

I definitely plan to have more games in future, but at the moment the priority is the Cartel warring system and fights, mixed in with various smaller Quality of Life improvements where I have time.

There is unlikely to be any new games in the near future.
