I would love to see more videos of the builds, as still images don't show the capabilities of a 3D animated game that was a work in progress. However it seems overly spiteful, and frankly bad business, for Game Freak to build a prototype of a game that has more working features than the released game.
I don't believe for one second that this shows cut content could have been left in the game without any further changes.
Might be fan demand?
A lot of fans complained abuot the over use in Rotom as Technology in Sun and Moon.
Rotom is the PC, A Phone, A Pokédex, A Drone, TV Cameras.
Perhaps they thought a Mini Map as well is too far. though they could have just removed the Rotom like UI, or better yet stop using Rotom in everything now.
Experimental Gameplay, and Lost Hope.
