I think it was this
Ultima 2 for the Apple II.
I still can hear in my head the weird sound of moving or something, like a weird screech. I played it at a local computer club for like a year, maybe one hour a month, until I saved up enough money to buy my own Apple II and buy a copy of the game for myself.
Different times too, my mom would drop me off at the club at like 6pm and pick me up at 8pm, and it was mostly a bunch of guys and maybe 1-2 kids. Nobody cared or batted an eye. That sorta thing would be impossible now, lol
