Not op but having played Rebirth, while overall very good, it suffers from the classic case nowadays of adding repetitive "chores" to do around maps, to artificially increase the length of the game with little purpose.

So far (only 6 hours in, but some friends who went further confirmed), Expedition 33 seems to steer away from that, being a lot more story driven.

It also has, by far, the greatest prologue I've seen in a game.

Worse thing so far, the UI in the menu does take a second to get. Particularly the selected state is way too subtle and a bit confusing at first.
