Actually my favorite part about this game is the story and where it's heading. They really do a great job at world-building (yeah, I know, it's more like coherent compilation and continuation rather than original ideas, but still...well done). I especially like the history and present of the political climate, factions, alliances, whereabouts etc. during the era of A:FTE - very rich, detailed and believable. And just like mentioned by previous forum members the initial game only started the storyline. We have yet to visit Pala Station and we all know that there will be be some nasty skirmishes between human Factions down at the surface.
I really hope we get to see UPP soldiers at some point - would be sweet to see their armored spacesuits with wrist-mounted guns in action.
What makes me feel positive about them being able to finish the storyline is that the game is selling really well, so there probably will be plenty of more content to come.
Anyways, I really dig the story and premise of this game (just wish that the game was scary and suspenseful with less super human-like Marines).
