Here is the facts, as I see them.
A. Many millions played Halo 3 MM; that is a fact.
B. Between 2007 and 2010, many millions left Halo 3 MM; for many different and varying reasons; that is a fact.
C. Bungie made Halo 3 and Bungie realized as did many players who left Halo 3 MM, that it was very flawed…no sprint, bad ranking system which unintentionally enabled cheating, selling of accounts and so very much more; fact.
D. Bungie attempted to fix some of the issues with Halo 3 MM by introducing sprint, AAs and other tings and removing competitive ranks, other than for Arena, with its Halo Reach MM; another fact.
E. Fact is that the many millions that played Halo 3 MM never, ever turned up to even play Halo Reach MM. This can be for many reasons but, I suspect that the major flaws with Halo 3 MM accounts for most of it and then the many new games on the market, which Halo now had to compete with. People simply did not come back from the Halo 3 MM days to even give Halo Reach a chance, thus, attempting to state that sprint, AAs etc are to blame or Halo Reach, is wrong. People left Halo 3 for reasons relating to Halo 3 and never came back; another fact.
F. 343i took over and continued along the path that Bungie started with Halo Reach; another fact.
G. Only half the first day playing population of Halo Reach MM turned up for Halo 4 MM. Halo Reach MM launch day had a peek around 1 million…Halo 4 around half million; more facts.
H. Many people that played Halo Reach MM did not show up for Halo 4 MM. Therefore, Halo 4 cannot be the blamed, but residual Halo 3 issues and issues with Halo Reach, as well as even more competition from other games can be; fact!
I. The hate for Halo 4 MM and Infinity is wrong/misplaced. How can 343i and Halo 4 MM be blamed for the state of things when the millions that played Halo 3 MM did not even show up to give Halo Reach a chance? And, if the millions did not turn up to give Halo Reach MM a chance and thus not turn up to give Halo 4 MM a chance either, how on Earth can an argument be mounted that some old Halo 3 MM versions is preferred by the wider Halo fan base over Infinity when that wider Halo MM fan base did not ever pick up an XBox controller, insert Halo Reach and/or Halo 4 MM and try it?
J. This wider Halo MM fan base actually is a myth! MM is no longer the draw card for Halo and never will be again. The large Halo MM fan base left during the Halo 3 MM days due to the major flaws with that MM variant. Over 9 million purchased Halo 4 and the vast majority did so for the campaign; that is a fact.
K. For those that actually did turn up for Halo 4 MM on launch day, BTIS and IS were number one and two most populated and have been ever since; that is a fact.
L. No matter what 343i have done over the past months to give the small remnants of the Halo 3 MM days something which they like, the fact remains that those Halo 3 styled play lists/modes are the least popular. Team Throwdown is sixteenth on the list, Legendary Slayer thirteenth on the list.
M. The Halo 4 MM population has declined since launch day. That is no surprise at all! There are many reason as to why this has been so. For some, it is because they did not like Infinity.For most, though, it is because of how modern day gamers are. They give a game a go and then move onto the next game, as there is so much competition out there that hardly anyone but die hard franchise fans play a single title to death. Rather, they play many different games and do not stick to one.
N. The inconvenient truth is that the 9 million Halo 4 game owners purchased the said disks for the campaign; Halo MM is but a very small part of what the Halo fan base likes; the millions that played Halo 3 MM never turned up to give Halo Reach MM a try; even less turned up to Halo 4 MM; blaming Bungie and Halo Reach and 343i and Halo 4 is wrong as the millions that left did so during the Halo 3 MM days and never came back, therefore, Halo 3 MM is to blame.
