Does anyone play any DOS games?

I know this is site is more 2000s and Gen Z oriented but does anyone remember playing some old DOS games, whether they played them back in the 90s or have used an emulator?

There is this Pac-Man clone called Pako 2 which is a very fun and fast-paced version of the game with a bunch of gimmicks and hazards. I have gotten hooked into it in recent days but it's shareware so it stops me at level 25, sucks I can't find the full version.

What DOS games do you play or are familiar with at least?
