I still play OpenTTD every now and then.
But back in 1997, I had the shareware version of Transport Tycoon and I’d come home from school (6th grade) in summer, about 20 minutes walk in 30 degrees heat - my dad would have the dodgy air conditioner on, I’d splash some water on my face and get down to some railroads.
It was a very good time and as an adult I’ve never recaptured that feeling with OpenTTD. But I still install it first thing in every distro.
