What I have seen of the main story through videos and etc (quite a bit), I agree the storyline is pretty....weak and contrived, and indeed purposeless, it's almost as if the game would be just as good to me if the main storyline didn't exist and they massively expanded some of the the side stories and exploration features, as good as they are nearly everything can be improved. If I was to play the game, I would want to completely ignore the main storyline and explore the galaxy (or bit of it they have created at least), but it seems to me to get what you need to actually do that you are required to play the main storyline. Of course in ED I have ignored the Thargoid stuff nearly entirely, except for the early parts where we were searching for the first Guardian bases but that was really exploration oriented and I wish there was more of it. I recently watched a video where the player was doing the progression to NG+7 final combat bit, and no thanks, that just looked entirely silly to me and completely uninteresting in any way.
