You'll no doubt have seen that some of the former devs from Bullfrog have just announced a spiritual successor to Theme Hospital (Two Points hospital). Both games, yours and theirs seem to have been in development for some time, so this very much feels like a coincidence that both are to be released this year!
I wondered what you thought about this in terms of the challenges it brings to Project Hospital and also any benefits. I thin your decision to go for real illnesses was a masterstroke (no pun intended) and immediately differentiates you from the 'other game'. I think this news also brings the benefit of no longer having people who are disappointed that you have take this particular direction.
