Our favorite on the C64 in Finland was a game where you flew a helicopter on a world map and had to find different countries by name. Not sure what the name of that game is.
Hahaha, I was just playing that game a couple months ago for the first time. It was pretty fun tbh. It's somewhere on Gamebase. Maybe in these results.
I played a bunch of different games in 1989/1990 that I only vaguely remember today .. would be wild to see them again just for the nostalgia trip.
