I’m sure many of you have great memories of the 1997 classic game from Bullfrog Theme Hospital. Unfortunately it is very hard/nearly impossible to get it working on Windows 7 (and Windows Vista if I remember correctly) even when using DOSBox. Thankfully this has now been made as an opensource game which you can play on PC, Android, iOS, etc.
A word of advice when playing on a mobile device (excluding tablets): Use the 640×480 resolution when setting it up- instead of ‘Native Resolution’ as otherwise the buttons are too small to press- I have a 4.3″ Motorola RAZR I and its just about fine playing on this at that resolution. You would struggle to play it on anything smaller than a 4″ screen, those of you with a 4.8″ Galaxy S3 will find it easy, but I would still use the 640×480.
