I noticed that pretty much all games I played in my life have been released after 1990. So now I’m asking those with earlier experience here:
Which games can you recommend from before that time?

But: they should still be fun in their own right and not just interesting to play in an historian sense of trying to understand how genres developed.

Games I played that are older than 1990:

• Tetris (classic for a reason)
• Pacman (interesting but simple)
• Prince of Persia (was too young to understand how to correctly play this game, I should maybe try to play it again)
• The Legend of Zelda (too old school and clunky for my liking)
