The graphics seem to follow a realistic version like Civ5, the UI is literally the same as Civ6. Interestingly, the soldiers are tiny, it could mean something new for warfare more similar to Humankind.
EDIT: now that I saw it, there are two healthbars for two different units on the same tile, but they are in different places on the same tile, interesting...
no no no its more like civ, bit with something different, where when you finish a age you choose the next one from a set pool of ages (you need to complete somethings to enable one or another). This is what I understand with the little information we have.
This looks really uninspired and under-cooked so far. A relatively unknown dev team combined with Paradox's appalling DLC strategies and my hopes remain fairly modest for this. The UI looks like they've essentially copied Civ VI which is... worrying.
