1 Is retroactively worshipped as the sacred cow of its franchise (Super Metroid, Final Fantasy VI-VII, Chrono Trigger, Mario 64, Fallout 3, Parappa The Rapper, Earthbound, Link To The Past and Ocarina Of Time)
Now now, let's not forget Kirby Super Star, Sonic 2 and Star Fox 64
2 Difficulty level that is either way too easy (Undertale) or nowhere near as hard as people say it is (Dark Souls)
Almost every other Zelda game VS Breath Of The Wild and Adventure Of Link
3 Belongs to the platformer, RPG and/or shooter genres
4 Is made by Nintendo, Valve, Naughty Dog or Square Enix
5 Clichéd, one-note and predictable storyline and character cast that gets hyped up to be the greatest thing since sliced bread (Super Mario Galaxy, Half-Life 2, Final Fantasy VII, Last Of Us, Chrono Trigger, Undertale, Earthbound, Mother 3)
6 Pretentious art styles (Braid, Rayman Origins/Legends, Cuphead, Dust: An Elysian Tail, Undertale, Wind Waker, Bastion, Okami, Valiant Hearts)
As long as there's no art style inspired by those 1990's hand-drawn 2D animated movies with talking animals *cough*The Lion King*cough*, then all is well.
Seriously man, those kinds of movies are overrated as heck and have bad fanbases. (is someone who doesn't like TLK)
7 Comic-relief villains as main villains (Hades from Kid Icarus Uprising, Fawful in Bowser's Inside Story, Wheatley and GLaDOS from Portal, Porky and Fassad from Mother 3)
At least I rather have a main villain be a comic relief than to be bloodthirsty, insane and seeking worthy opponents.
8 "Saddest Game Ever" label (Mother 3, Cave Story, The Last Of Us, Undertale, etc)
9 "Memetic Sex Goddess" characters (Toriel, Alphys and Undyne from Undertale, Lammy from Um Jammer Lammy, Rosalina from Mario Galaxy, Gardevoir from Pokemon, Samus from Metroid, Lara Croft from Tomb Raider, almost every female Sonic character, etc)
Almost every Sonic character? God, I hope that is not true. Now I know why Cream the Rabbit is treated horribly by fans and used in pairings when she shouldn't be.
Hey Joker, wanna rev up your Harley?
10 "Funniest Game Ever" label (Bowser's Inside Story, Conker's Bad Fur Day, Psychonauts, Undertale)
The Contenders
11 Is treated like the Holy Grail just because it has Disney characters in it (Kingdom Hearts, Disney Infinity, any Disney licensed game)
12 A big mess of a crossover that does not fit with a cliched original hero of light who fights dark creatures and a cliched dark villain, complete with generic character designs (Kingdom Hearts)
13 Villains who bear a resemblance to Karel from Fire Emblem (Sephiroth from Final Fantasy VII, Ansem from Kingdom Hearts and Xemnas from Kingdom Hearts II)
I hate this stereotype. This is why so many fans think Karel is evil when he is not.
14 "Worst Game Ever" by critics just because of their flaws (Sonic the Hedgehog 2006, Bubsy and a dozen others)
I personally liked Sonic '06, but I acknowledge it's flaws.
