If the gameplay isn't good or if the choices don't really matter then the only thing keeping my interest is the story and if that isn't good then I just don't play and uninstall.
This also goes for normal games too. (like hellblade gameplay isn't very good but the story is why I kept playing)
I played this years ago after my legacy, was disappointed to see it was abandoned but glad to see it isn't any more.
Is the newest update worth a play again or should I wait a few more updates presuming it will get more?
if you can get past how big this game is and play it I does have a lot of content, however I don't think its worth to download every time there is an update, I would probably wait till its done or they figure how to optimize for a smaller size download.
