Very fond memories of playing this circa 1999/2000 in my cousin's house. We would jump on the PC and swap between Theme Hospital and Small Soldiers. It really helped nurture my love for PC gaming and wanting our own family PC. Previously, I would have only played PC games at my cousin's house or my Grandmother's house (Quake).
We eventually got one very soon after, and I would play Age of Empires and so many more games down the line.
I like to think my fondness for PC started with games like Theme Hospital and Small Soldiers.
