People are really shortchanging the Genesis here. Thunder Force 2+4, Wings of Wor, Elemental Master, MUSHA, Bio-hazard Battle, Gaiares, and Sagaia are all good shooters, and some of them are just as good as anything the Duo has. If you include CDs and imports, you have even more quality entries, like Robo Aleste and Gleylancer. Yes, the Duo kills it by virtue of outnumbering it by a vast margin, but the Genesis is a more-than-respectable second.
