GTA 5, when it launched some people criticized for... reasons... I can´t find a single flaw in that game but leave it to the internet...
Also, MGS5 is a fantastic game and the mimimi crowd also found stuff to complain about.
But, to me, the grand prize goes to one of my favorite games, SILENT HILL4: THE ROOM.
It is a amazing game and people bash it to pieces.

Sonic Boom Rise of Lyric. It's an amazing game. The levels are well thought out. The gameplay is well done and the frame rate is better than most games made within this year...

Said no one ever

Mass Effect 3 :)

DmC

Actually I think this is the best example. One of my favourite games ever.

Which Mario Party games?

Cant agree with Final Fantasy X-2, but lets stay in topic:

Super Mario 3D World - Great game.

Monster Hunter series in general. But thats more of a VGchartz thing. Only in here people are unable to recognize the magnificence of this franchise.

Suikoden V - It sold so bad that the entire franchise died. Yet I find it to be a fantastic JRPG as a whole, with some of the best characters in the series.

I know some are better than others but I've played them all and honestly if you just have a good group of friends it's not going to really matter.   Each game has their fair share of fun mini games.  Personally I didn't mind the whole 'kart' thing when they changed it up in Mario Party 9 & 10.

Matters to me! Why play the crap Mario Party's when you can play the good ones :P

2,3,5,6 & DS are the best ones!

Tokyo Mirage Sessions #FE. The game is just fantastic in every aspect. Easily one of my favourite games of this gen. Yet, fans of both FE and SMT complain about some seriously silly things about the game that hardly matter (mostly censorship).
