It's funny.
I've been waiting for this game ever since it was first announced (7-8 years ago?), but I still went in blindly. I think I only saw one gameplay video and that's that.
This, in return, allowed me to enjoy the game as it was. Beat it 100% the other day and enjoyed it thoroughly.
But reading back all the features that were promised (pathline choice mattering; 3rd person and so much more), I do have quite a bittersweet taste in my mouth.
They're probably going to be pumping out DLC's to save face, but we'll see. No Man's Sky did a complete 360 and was in the similar situation - overhyped to the brink, but when it came out, it essentially died out in the first couple of days. Then they started adding patches and ''recreating'' the game and apparently, it's in a great place now.
We'll see, but still, if you're on PC; I suggest trying it out. :)
