Halo 3 is way different. It was a cliffhanger of sorts, and it only had one path it could take, making a sequel easy.

Mass Effect 3 ends with multiple different paths that would make a sequel almost impossible.

Now, as to your Halo 4 points, I have a few comments.

Spoilers for Halo 4 Follow

As someone who has played and beaten Halo 4 on the day it was released, I have to ask, just what in the h*ll are you talking about?

There was no Cryptic message that warns of a future enemy, we already know who the enemy is (if you played Halo 4 that is)

Additionally, what "Certain Ship" are you talking about? The Infinity? The Didact's Ship? And for that matter, what does the ability to rip a Reaper in half have to do with anything?
