Dear lord... people learn what spin offs are. The main story of Halo 3 revolved around a Spartan, Master Chief. Just because the game breaks away into a spin off doesn't mean it's a different universe. The same events happen in spin offs. Master Chief blew some Halos up already. Spin offs are set in the same time period. Spin offs are set in current events. Just because it is "Halo 3" doesnt mean it isnt a spin off.
