I enjoyed it very much. Seems deeper than Civ, but maybe that’s just because it’s different.
I very much like the combat system. Armies can have many units/types in them as they move around the map, but when combat happens it becomes 1 unit per hex style combat. Terrain height gives advantage in defence and extra range for ranged units.
Diplomacy so far seems more interesting and choices seem to change a bit as eras pass.
Cities and territory control is very different. The choice between few cities covering large areas or lots of smaller cities is an interesting dynamic that the demo only hints at.
Game is great to look at.
Overall the game is a fresh take on Civ style game play.
