Personally, I have witnessed a lot of the all encompassing "the fans don't want this" commentary in various places, and all I know is they are not speaking for me. I'm personally looking forward to giving this game a whirl, even if the always lovely "you're not a real fan" criticism follows.
I've mentioned before that in my perspective, Alien is a film franchise, and any of its side dishes are not accepted as canon to me (like most of the casual movie going public). Not video games, comics, or novels. But what I do hope comes out of this product, is more goodwill towards Amanda Ripley, enough to convince studios to proceed with her story theatrically, with an adaptation of her alternate media stories. That's my hope at least, and if this mobile game is received well and very successful financially, it can lead to that.
