I am playing this right now and love it, though the learning curve is steep even for a Civilization veteran. This is what Civ VI or VII could be if they didn't try to dumb down the game to increase the audience.
I would recommend everyone play their first OW game on the easiest difficulty, regardless of their experience with Civ. It is a fair bit more complex and Civ skills do not directly translate well to OW even though the two games look graphically similar.
