Something I've always wondered...do we know why Halo 2's development was so poorly managed? I know Bungie was breaking new ground with online multiplayer, but why wasn't a three-year dev cycle long enough for them? It's not like they needed to devote part of their team to Halo 1's multiplayer maintenance.

They got Halo 3 out the door with no problem, despite it being on brand new hardware. And 343 seems to be so far ahead in Halo 5's development that they can do a public beta test a whole year before the game is released.

So what's the story with Halo 2? I remember from the documentary that they ran out of the time and had to scrap a bunch of campaign levels (like the ending), but why were they in that position in the first place? Did they have some false starts? Were they just overly ambitious?
