VERSION 3.0
Still on the list:
-Nightmare on Elm Street (this one is a stretch - at best a "cult classic")
-Omega Boost (a great game, but a really obscure one and not even something with cult status)
-Illbleed (same comment as Omega Boost)
-Landstalker (your impulse said no: you should have stuck with it)
-Otogi 2 (too obscure, middling reviews, not amongst best on system or genre)
-Golvellius (SMS) (too obscure, middling reviews, not amongst best on system or genre)
-Exhumed (SS) (too obscure, middling reviews, not amongst best on system or genre)
-Zillion II (the first one could maybe count, this one not so much - even if it is better…both suck, by the way

)
-Mary Kate and Ashley.. (lol)
-The Death and Return of Superman (is this even considered a great game amongst comic book game fans? Because it certainly isn't even in the top 25% of best games in the Genesis library)
-Valis (middling reviews, HG101 says "decent at best")
-Batman Arkham Asylum, Uncharted, Bayonetta, Uncharted 2, Lego Star Wars games, COD4, Dragon Age, Dark Souls, etc. (too new, unless we're gonna extend this to "modern classics" - and even then some will still not be good picks)
these games have wisely been taken off the list:
-Darkwing Duck (unless you buy the argument that Capcom+Disney always equals classic, I don't see this one approaching the heights of Duck Tales or Chip N' Dale - it is just a much more mediocre title)
-Frogger 2: Swampy's Revenge (just because noise likes something, that doesn't make it a classic)
-Kirby 64 (see "Star Fox Adventures" below)
-Cybernator (still not buying this, even if it was once in an EGM list)
-Starfox Adventures (just b/c a series is considered a classic doesn't mean all entries are. this one, by overwhelming consensus, sucks)
-The flinstones: rescue of dino and hoppy (old + rare ≠ classic)
-bugs birthday blowout (this one is a stretch - at best a "cult classic")
-Yugioh Double Pack (No, sorry)
-Quest for Camelot (another game that is pretty shitty by almost all standards)
These games were foolishly played anyway, so the player learned their lesson the hard way:
-Jumping Flash! 2
If you did take something off and I missed it, let me know!
