"Elves are very good at board games, and I'm NOT an elf!"
Only had one play of this game but was thinking about different rooms that could be added. Here is the Delivery Suite:
Delivery Suite - when taking the Admit Patients action, a player that has built a Delivery Suite can also admit a patient into it (of any colour). When adding a patient to the tile, take a matching patient cube of same colour from the box and add to Delivery Suite (there should now be 2 cubes of the same colour in the Delivery Suite). If this isn't possible, the player cannot use the Delivery Suite. You can spend an action to 'cure' patients from the Delivery Suite - this 'cure' is not the same as the normal Cure Patients action.
It might need a bit of balancing - perhaps you can admit up to 2 patients into the Delivery Suite (using the normal Admit Patients action), adding up to 2 matching cubes (up to 4 cubes may be on the Delivery Suite). 'Cure' from Delivery Suite by using an Action.
