After a couple of weeks of playing, here are my thoughts:
1. The game looks beautiful, and many of the changes are positive.
2. The game is different, which is cool. Keeps me on my toes, forces me to re-think strategies that were on auto-pilot on previous versions.
3. It's extremely difficult to figure out what each picture is. I have no clue most of the time. I didn't even realize rubber was now in the game - I thought that was rice.
4. My biggest issue - the game is ultra-complex now, and while I completely understand that the Colopedia updates take time, the lack of updates or more explanations on the in-game pop-ups/mouse-overs makes the new gameplay doubly frustrating.
Bottom line... I'm enjoying the game quite a bit, even if I simply don't know what to do with many of the new resources because there's a lack of "connect the dots" explanations between resources/terrain, professions, buildings, and final products. For instance, some new resources are used to make something else, some are just there for increased food production or some other reason I can't figure out. Stuff like fruit appears to just increase food production, but there are no terrain improvements or further refining/production associated with them, you just stick someone in the field to pick it. The explanations in the Colopedia look identical to some of the other resources that we actually do use to make something else. But take coal, for example. I have no idea what to do with it, and I can't find a single explanation between the resource, terrain, individuals, building, or potential product that tells me what to do with it. By trial and error, I think I've figured out that 6 coal and 6 iron will produce guns, but I lucked into that finding, and I don't know if that's all it can be used for. It feels like there are dozens of similar "figure out the puzzle yourself" situations throughout the game. All of the animals, people who can hunt/herd them, and produce something out of them are similarly difficult to figure out. I still can't figure out what wild bird feathers are used for. Same thing with all the different types of wood.
Anyway, just my two cents. Thank you for the game. I'm trying to figure out how best to play by trial and error, but it's still fun and that's the most important thing.
