It depends what you expect as a result Please check following link: http://www.marmoset.co/toolbag/learn/pbr-conversion It's quite descriptive and easy to understand explanation of map conversion to PBR...

According to my (therefore very subjective) preference, i would say some form of life support and "robotics" features are mandatory for 1.0, since the game feels somewhat incomplete without them. On the other hand some small bugs here and there can be expected on the release, but ofc no game-breakers should occure.
