Erm too hard to say really. Out of the games I had back then for both consoles, I would have to say that the SNES edges it with games like Super Mario World, Donkey Kong Country, SM All Stars, Super Star Wars, Zelda and Mario Kart, but Megadrive was also amazing: I had a Sonic compilation with sonics 1 & 2 and mean bean machine, columns, italia 90, ms Pac-man. Ah... great times.
