I also have to agree and choose the original Air Zonk over Super Air Zonk. Not only is it one of the most bad ass colorful hueys around , its freakin BONK IN THE FUTURE! sorry nostalgic moment, I had that game come with my first ever TG16 I had bought (along with Dungeon Explorer, Miltary Madness, Bonk1 and other classics) .
Anyways, I didnt get to play SAZ untill 7 years later. I was in a huge DUO-R binge of getting tons of discs delivered to my house, buying random japanese titles and this was in a bundle. I loved it Im not saying its bad at all, but AZ was easier to hop into. Im not a shooter fan so I cant really get technical on comparisons, plus its been so long since I played both.
Bottom line is while playing Super Air Zonk, I just wanted to hop back on Air Zonk
