While I do like the concept of civics, I'm really disappointed by two things:
1) Syncretic evolution - While the Syncretic evolution trait might be pretty neat, as the boni from strong and proles (+extra traits?) is pretty neat, the fact they are completely random is severely disappointing. It basically just means I would have to do more restarts to get a situation I like.
2) Meanwhile Mechanist just seems completely useless, it means taking a massive hit to early production while you build up an energy surplus (which could be disastrous if you dont have a lot of potential energy mines nearby), just so you can get some pops that give a very minor bonus to food and minerals? The robot tech is already easily accessible very early on, so It honestly seems like it might be more of a burden than a bonus. I can tell you now, that even though I love playing with synthetics, I would never once play with this civic.
3) Hive Minds - Essentially, playing a Hive Mind is just like playing Stellaris on release. While I think its good that internal politics should be gone in a Hive Mind, the fact that you would have almost no control over anything is a bit disappointing, and it seems like you are pigeon-holed into a very specific and narrow type of hive mind. Please, please, please allow multiple types of purging if only for the sake of sanity.
Overall, while I have been very excited about Utopia, this developer diary was the first one that was actually flat out disappointing.
