If you want to play a deck builder I'd recommend Monster Train or Slay the Spire over this. It feels very complicated but also very random. A little more like a slot machine that a strategy game.

Pretty tight game loop, leads to very fun game. On improvements: long term I can envision some expanded Conquest with perhaps missions and a custom culture (with affixes), and on the short term I can see improvements to use Random as a civilization, expanded "battle length" with more starting health to be able to see late age more often, ...

I played a bunch of the demo and enjoyed it a lot. This game is the perfect blend of simple and tactical, which makes it easy to pick up and play for a few minutes or stay for hours. The full release is even better with the different nation bonuses.
