Yeah, but I always find it very interesting to see how hard the programmers have tried to puch the systems capabilities! On a certain other 8-bit system which shall remain nameless for the purposes of staying within the thread rules  there is one particular game where they tried to do a bit of 3D graphic sprites (not with the glasses before anyone starts!!!), and it didn't quite come off, but it really wasn't far away, and impressed me with its ambition! 

if ya wanna see the street fighter nes games, register at dgemu.com and do a search for "street fighter"
Scroll down to the NES section of hits and here you will see all dumps of NES SF2's

Any good ones?  I thought Master Fighter 3 was good, but it didn't play right on any of the emulators.
