For me , Megadrive /genesis si far far far superior than snes for action games , adventure games, sport games, beat em all games shoot em up games, racing games , plateformes games... just rpg is for snes and i am not fan of rpg, you know what i mean, The difference is enorme.

For the master System, you take, Ninja Gaiden, R Type, Sagaia , Castle and Land of illusion, Deep Duck Trouble, Phantasy star, Golden axe Warrior, Submarine Attack, Power Strike, Sonic Series, Wonder Boy Series, Kenseiden, Fhantasy Zone, Zillion 2, Spellcaster, Shinobi , Aerial Assault , Bubble Bobble, The Lion King, Alladin, Asterix, The Flash, American Baseball, Tecmo World cup 93 ... and you compare with nes, you will see, master system is the best.

Ciao noobs.

From personal experience, I can tell you that the NES kicks the crap out of those games with one foot behind its back. And you spelt Aladdin wrong ;).
