Tetris.
@pamela Still a sucker for Wolfenstein 3D & Doom (the DOS versions), and a lot of the the 2d shareware games: Commander Keen, Jill of the Jungle, Duke Nukem 2d, Cosmo's Cosmic Adventure, etc.
Also, Scorched Earth/Worms and the real-time counterpart "Liero" (an open-source iteration may be available in repos)
Stretching back a bit further, I still get a kick out of playing "Lode Runner" and "Knights of Legend"
@pamela SMB3, SMW. Oh the hours spent playing those.
I had them on NES/SNES. Our SNES came with All Stars + World cart, so I played both there. Bought them for GBA. Bought them for Wii. Bought them for 3DS. Play them on my Switch.
Except for the years when I played almost nothing but my N64/GameCube and PC games, I've never not played the classic Marios.
