@imunbeatable80: The story as a whole is decent, and if anything the planets are different parts in the tale of what happened told out of order. For instance the first area of the game, Xenophon, is also the last chapter as far as the fate of the expedition is concerned and the game works slowly backwards from there. Then there's everything happening in the present and how that's linked, so it's layered without ever being too difficult to follow.
They're very different games in most respects, but there's a connection you could make to Return of the Obra Dinn. In both cases you've got a pile of bodies and need to use the clues to work backwards and figure out what happened.
