You must be a fan of "fuzzy math". You state some 90,000 on Reach.......ummm out of the nearly 9,000,000 (that's nine million) players the bought the game only equals 0.01%. Those have roughly been the numbers for a long time.
A 'majority of the population" has left the series, it would appear, because of Reach. The Halo population, fans or however you want to refer to them made their statement about Reach by not playing it, that was their vote. Just because the "current" numbers in the forums favor Reach, simply because these are mostly the fans of Reach, bears no actual relationship to how all fans really feel in spoken words.
When a member of this, or any forum, makes statement about a love of prior games, wanting the "old feeling" back, previous ranking or weapons use or make any reference to the past games it does not mean we want to live in the past. It just means we want a game that resembles the qualities of what millions of us have fallen in love with while continuing to advance the experience.
I respect the fact that people truly enjoy Reach, even if it is only 0.01% of the people that bought it. Remember also, that of that 0.01% there are those like me who still play it on occasion with the friends they have had since Halo 2 and Halo 3 days and enjoy the fellowship of those friends even while playing a game we really don't like.
The future of the series is dependent on one of two things in my opinion. 343ind. has to either find a way to get the majority of the fan base back playing by offering a game that they can enjoy initially, and long term, with a quality campaign and a distinctive MM while appealing to new players of the game or they have have to find a new fan base that would include those who would play the game simply because it has a Halo logo on the box. Every single note worthy statement I have read indicates that they are attempting the first thought of getting back to Halo's roots. They will be exploring more of the Chief's personal feelings in campaign and the traits that make him what he is. They will be offering new MM experiences while still offering the previous feel for the game. They want a success, they want to make a game the fans can truly enjoy for a long time, they want us to be happy. I trust their efforts with blind faith based on the comments they have made. I trust the series in their hands.
