Phil-X-I feel that the series would be a lot more successful if it was still made by bungie
Its a large portion of the same people.
Don't think Bungie would have done much better, the campaigns in each game were gradually getting worse, although none were bad and 343 did by far the worst with Halo 4.
Halo 2 had the best multiplayer ever, but if they kept that the same people may have gotten bored and complained that they are just recycling the same thing over and over. The only thing I play from Halo 4 is SWAT which I havn't touched in months. They really screwed up the ranking system in 4.
Part of me wishes they would have just stopped at 3, but I will always be excited when another Halo game comes out.
