Played it quite a lot. For some reason I can't get into in the same way as I have done with all the previous civ games (which is probably a good thing for Aurora development) .
Me too (both on playing and not getting into it as much). I think part of it is that they've made it a lot harder to understand what's going on - for example I still don't know how to figure out which cities have which amenities and how getting more would raise them for a particular city. And it's not clear if the promotions available to apostles are one-time-only (like wonders) or if they're randomly chosen and able to repeat. And how many points of which religion are in a city, and therefore what the impact of trying to convert it will be. I know there have been 1/2 dozen things like this that I had to stumble upon in the GUI: "Oh, THAT's how you find that out".
In addition, it feels like a lot of the individual game mechanisms are less rich. For example, it doesn't seem like city-states cry for help against other civs invading them any more - my recollection is that this would happen in Civ V.
On the plus side, I think I like the whole "boosting" concept for tech and social research. OTOH, I'd REALLY like it if it would give me a warning when I'm 1/2 way there on an unboosted tech so I could switch to another one while waiting for the boost.
