Really worried about a lot of different feedbacks on the UI ; I mostly watched videos of YouTube civ streamers more than video game publications reviews than I trust for many game genres but less for games that take a lot of time to truly get the feel of, and most of them seem to really enjoy the gameplay (with some small caveats on how age transitions are managed) but they all complain (with fair points and concrete examples) about the UI (and some UI adjacent stuff like no auto exploration for recon units).
I guess we will get an early patch but that's worrying, finding the relevant info is key in 1 civ game, and tediousness could hurt replayability a lot.
