Popular in the UK and Brazil, I never knew anyone who had one here in Greece. What are some of your favorite games and memories from it? It could be any iteration of the console.
My first system was a ColecoVision, but Master System is really the first system I have vivid memories of from childhood. I think the Master System overall was my favorite part of being 4-6 years old - playing Shooting Gallery, Fantasy Zone, Ys, Missile Defense 3D (I think that was the name), etc., It also felt mysterious (?) to me because a.) I was the only kid I knew with one and b.) things like the hidden game (I forget the game exactly) that would come on if turned on the system with no cartridge inside.
