Horse races
I feel that being able to bet on horses would add a lot to this game. CasinoRPG has this vast 3d world but it's underutilized. Begin able to bet on a race, then going outside to see it in real time along with everyone else would be pretty sweet. Plus, it would add a social aspect to the game. Viewing the race should not be required, but going back to the casino after the race finished to collect any winnings should be (like a real casino).

This is something that we definitely plan on doing, along with other similar types of activities. This certainly fits into our vision of building a sprawling city with a focus on casinos, but not limited to them. Thanks for sharing the idea!
