It's the other reviews getting passes that I have problems with. Halo MCC is not a 9 game. I have played it. I like it even. It's simply not a 9 game in its current buggy and unfinished state and that should be reflected in these reviews point blank. I think games like KZ were torn into for not being finished.
Fair point on MCC but I think that there are a number of other factors in play in regards to why that game got 9/10 reviews:
-Reviews are often more focused on single player elements, value for money and content, as opposed to MP interaction. Halo MCC was excellent in this regard despite the bugs.
-Many of the reviews came out
before release and were generally higher than those that did came out afterwards. IGN and Gamespot both gave lower scores than they normally would have. IGN is actually a special case; the reviewer loves Halo 2 with passion and he even stated in his review that he was not willing to deduct points over bugs that 343i would eventually fix. He gave Halo 4 in 2012 9.8 and he gave Halo 1-4 in 2014 9, lol. So I guess there is a level of
reviewer inconsistency.
-The biggest issue is still matchmaking. The core experience; Halo 2 Anniversary, while not perfect, was certainly 9/10 for many reviewers. This may be partially because the bugs seem to affect people differently; one person gets 150 games and another gets only 2 games. Single player bugs especially seem to be concentrated in Halo CE and Halo 4 based on my experiences. Even then framerate drops were still above 30FPS, while Unity dropped to more uncomfortable levels.
-Halo has generally had smooth launches; reviewers probably
assumed the bugs would be ironed out by release day. What happened with MCC surprised most people, aside from the crashing issue which was seen pre release.
TLDR: Reviews based on content rather than presentation due to assumption of launch day and patch fixes.
So yeah, MCC has a higher metascore than it deserved on launch day but there are a variety of reasons why aside from potential bias.
