Are there some bugs? Yes!
Are there some needed UX improvements? Yes!
Are there some design issues that need fixing or improvements? Yes!
Do I like the 2.0 update? I love it!
Despite the problems, I really like all changes. It now feels like you have deep interwined mechanics (military + culture), different playstyles and decisions to make (tech system) and the UI adds so much immersion and beauty to the game. Also peacetime is cooler with the new building effects, civ value and Great Wonders. While I think the late game balance of the economy might need further tweaks (need to test it and wait for your feedback folks), it's definitely way better in the early and mid game - that's my current expierence.
I really hope they fix the ongoing issues and then I'm looking forward to play the game further, but I'm already eager for the next update roadmap too^^ But 2.0 is for me the turning point of the game! Just hope the updates won't stop now to make the game even better!
