The Gameboy & in fact, all games consoles completely passed me by - my experience of hand-held gaming was Donkey Kong and TomyTronic. Now I'm going to have a chance to see what I missed out on - sort of :)
My DS came with Pokemon Yellow, F-ZERO, MarioKart SuperCircuit, Metroid Fusion and Fire Emblem. They are all among the greats on Gameboy.
In fact, I'd say one of the things that helped the Gameboy succeed was that it had so very many good games.
