I still remember, I saw the SNES at a neighbors house when I was 3. We already had the Sega Genesis at this time, and an NES.
I was not really that impressed with the SNES. I was excited that it was new, and I wanted to have it but then while watching the neighbor dude play Super Mario World, I thought to myself "Castle of Illusion is more fun.", so I wasn't really upset that I didn't have it to play.
Super Mario isn't exactly the most graphically impressive game. Considering that I had Mario 3 and had just finished playing it, I didn't see what was Super about it. I honestly thought it was just like, an expansion thing that I could find in the used game bin at the game store.
I didn't really become impressed with SNES until I was introduced to Street Fighter II and Mario Kart. Until then, I was always playing Genesis because Sonic 2 is the best thing ever when you're a little kid hopped up on coke and twinkies.
The coolest thing for SNES to me, still, to this day, is the Super Scope 6. That is the best part of the SNES. Those games were awesome. No lightgun setup was that f*cking cool.
My aunt/uncle had Turbo Grafx, and that is where I first experienced it whenever we'd go over there for some family event.
It ruled. I always thought it was more fun than the SNES/Genesis as far as game variety went. This is probably because they had Bonk, KC, Silent Debuggers, Dungeon Explorer, Bloody Wolf, Neutopia, Alien/Devil Crush, Blazing Lazers, and R Type.
That's like, a power house of variety right there.
Basically though, I never got concerned with which was really better, because each console had something I liked more.
Squaresoft defined SNES for me, action games on the Genesis were way better, and TG was my arcade-quality machine.
Who the hell needed to go to the arcade to play shooty games when the TG did it all from my house.
