SMB3 -Same as above
Castlevania -Granted
Mike Tyson's Punch-Out!! -Already mentioned
Balloon Fight - more of a mini-game than a full fledged game. Who would pay money for it?
Excitebike - Granted
Kung Fu - Never heard of it
Metal Gear - If you say so
Mega Man Series - Granted
Ninja Gaiden -Already said
Paperboy - Okay
River City Ransom - Okay
Teenage Mutant Ninja Turtles 2 and 3 - Three was alright, but 2?
Wario's Woods - This didn't come out twill well after the SNES did
My point is that even though there were quite a few good games on the system, there was a BUNCH of crap as well, and many games were so friggin hard that even if they were otherwise sound, nobody could beat them. (Battletoads, anyone?)...
