It's a new term I'm trying to coin. Basically, it's when anything got less attention or sold less than it deserved. Anything that's good, but didn't sell to well so there probably isn't a follow-up. I'll start.
Things that suffer from the Underrated Curse:
-EarthBound (SNES)
-Nintendo Virtual Boy
-Sega Dreamcast
-Jet Grind Radio (Dreamcast)
-Nintendo Gamecube
-Nintendo 64
