But they didn't end in the same way at all.Eldritch Warlord said:Just be honest for a second, Halo CE ended in exactly the same way and no one (to my recollection) ever said that it was a cliffhanger.
CE ended with a pod adrift in known space waiting to be rescued, after a heroic escape.
3 ended with a pod adrift in unknown space, heading towards and unknown planet, with no hope of rescue.
Very different situations.
The first implies he'll be fine, it's just too boring for the story to deal with, the second implies that things are very bad and something very story worthy will have to happen for everything to be okay.
I can agree, by a matter of definition, that 3's ending was not a cliffhanger. But CE's ending wasn't even a sequel hook.
