Taking a look at Two Point Hospital reminded me to look back at the original Theme Hospital, which is currently on sale at gog for $1.49 or at its regular price on EA’s Origin for $5. What with EA being the company that bought Bullfrog and drove it straight into the ground you might want to buy it from gog who *checks notes* routinely hires shitlords to manage their twitter account. Ah, well, at least it’s cheap.
Either way, you can play Theme Hospital through the Dosbox variations gog and Origin provide, or via an open-source engine called CorsixTH. That engine is available for Windows, macOS, Linux, and Android. Just be prepared for ancient video intros and lots of midi music blaring through your brain.
