I give five stars for replayability, depth of strategy, etc ... all those ineffable "qualities" are perfect here.

My final rating remains however only four stars due to the inconsistencies of user experience across different devices, and extremely reduced performance when I use simulated graphics as opposed to enabling the native GPU. I don't know whether this is a mode that could be coped with in some way, when detected; maybe reduce AI computer power, or remove some animations in the rendering.
