At ten years old, I had a MSX2 HBF 700F from Sony with Microsoft system and Konami games: Vampire Killer (Castlevania) and Nemesis (Gradius). With two cartridges slots that give you special stuff if you put two different games sometimes. I can program it to make my own stupid games and store them on a floppy disk. Macadam Bumper and S.E.U.C.K. where also on this machine. Games where you can create. As a consequence, I am now running a video game studio.
