Likely... there is only one ending that cannot easily be achieved. The rest are trivial and require very little prep.

True; I was forgetting that you can save before triggering the endings. You don't have to replay from square one all the way through. Still, the harder ending (I think they called it the "fear the reaper" one?) was the best I think. The saddest is the one on the space station, that one was oh my god, gut-wrenching! But I also liked the one with the Nomads :)

>"fear the reaper" was the best I think.

indeed, also the hardest by far - all enemies are max level.

The hidden ending that actually leads to the same ending, just via a different path?

the hidden is called 'the star'. No spoilers, etc.

That's not the hidden one that one is given to you on a plate.

The hidden one is different: that's the one where you have to wait for a dialog option to appear and has a prerequisite that is a little harder to get then the prerequisite for "the star".

True that - it's the Sun, Sun being a star, I got them mixed.
