I still own every Sonic game over every system excapt one called Chaotix, I forget how its spelt now, but I will have my MegaDrive, with Master System adapter with all the sonic games, my GameGear and the Sonic games on that and also a Master System converter for that too, the only Sonic game I wasnt too fond of is SonicCD as now I play it it seems to have a slow response, but Sonic does indeed rule it was one of the reason I have all the Sega consoles still, didnt see Mario or any NES/SNES games do that for me, and yes that "SSSeeegggaaa" is a VERY strong memory from my childhood.

Just my opinions, I dont want to get blasted for speaking a lil bad about Nintendo
