> games you played as a child
If you have a PS1 or PS2 I'd recommend Ape Escape. It's my favorite PS1 game and I spent a lot of time with it as a child.
There's also Crash Team Racing which I played a whole lot of. And great thing is that if you don't have a PS1 or PS2 then they're making a remaster of it for PS4, Xbox One and Nintendo Switch!
I spent A LOOOT of time with Rollercoaster Tycoon 1, 2 and 3 on PC. Not sure how compatible 3 is with current PCs but 1 and 2 are available on GOG and run great. I'd recommend running it with OpenRCT2 as it makes it a lot more compatible with current PCs (but it should work fine without)
I played a lot of DOOM and DOOM 2 too but they might be too old these days with the 2D sprites in 3D space and such.
