It's because the publisher has put out multiple games in the "ENDLESS" universe, so it's a shared world kind of thing - I agree it's kind of dumb. I haven't played this game, but I did play the 2D "Dungeon of the Endless" which I liked a lot. To my knowledge, that game serves as a kind of blueprint for this higher budget release, so I'm looking forward to this one. Hopefully it's not shit.
