A Hospital where you have the ability to either treat NPC patients or REAL patients. This would make roleplay, which feels as if it has been neglected recently, more immersive. It would be a LOT of fun to walk around in a cast, and would get a lot of positive feedback. You could make it similar to other hospital games with realistic hospital items ( that follow roblox TOS of course ) but scanning for broken bones, a toggle for which injuries you'd like, or even dental treatment. It would boost engagement and keep people wanting to come back, possibly leveling up easier. You could alongside it add NPC Doctors, Car Crashes ( if you so choose, ) and NPC Patients. Just.. don't add back hospital bills, or make them cheaper.
