FFXIII-2 is not well reviewed.

http://www.metacritic.com/game/playstation-3/final-fantasy-xiii-2 

Effectively 8/10, plenty of 9's, most people agree it's better than the original, with 53 reviews.

When did 8/10 become a bad game/ not well-reviewed?

I didn´t knew that it was almost in the 80s i tohought it was somewhere 60-70.

They'll always be reviews that this, often reviews that are written by a reviewer who has no interest in the series, a reviewer who has a vendetta against the series or a review which is written by someone who flat out dislikes the game. The fact the score is more than 25% off the average shows that there's something up with the reviewer with this particular game. It happens. But it by no means represents the general feeling towards the game.

Most other examples include Jim Sterling with FF13 or Sonic Colours, or EGM with Xenoblade, or G4 with Skyward Sword. Every game will have a negative review written for it. It's the way the world works.

The assassin's creed games! Though I think I will finally play Brotherhood and Revelations this summer.

If you didn't like the first two, forget about the other two. They are worse. This comes from an Assassin's Creed fan.

all halo games(excluding odst and halo 1)

Yeah, I honestly do not understand what the fuzz is about with these two games. Watched one of my friends play them both now and then, just seemed incredibly slow and boring to me.

Then again, I love certain games that others think are boring so we're all different I suppose.

That is just what I was going to say.

Most normal sports games.
