YouTube has many channels with playthroughs of old games as well. (old for me is the 90's and early 00's since i'm in my twenties) You can find things like the old Lego PC games, old educational games like Physicus/Bioscopia, kids' games like Putt-Putt (not in the least because they have a speedrunning community), and much more. It's been a great resource to go back to the stuff I played growing up.
