In quite a few threads, gameplay concerning rivers has been often mentioned. Some reviews concerning naval units traversing rivers while others about increasing the importance of rivers and coastal tiles. There are some progressive infrastructures targeting rivers that focus mainly on food and industry yeilds, but I believe there is an argument to be made for coin to be included as well.

From what I have seen this actually occurs on the tile numbers but is difficult to see as the background becomes green or red (increase or decrease) instead of remaining white. I have difficulty seeing red/green colors... so I'm not exactly a fan of it quite yet. 

As you mentioned being into history, what did you think about the cultural transition mechanic? It is quite a change from other historical 4Xs, so I'm interested in how you feel about this. 

I read a few threads, I made some bulletpoints during gameplay to include in my feedback, I didn't include many of them as they were already mentioned in other threads. I didn't read all though and probably missed about others bringing up the rivers. 

The cultural transitioning is very interesting, and I believe Humankind is on to something here. But, this is how I'd have loved to have it being done:

Cultural transitioning shouldn't be like it is now, not exactly, but almost. Now you get some stars, doesn't matter which of them and then you get enough to advance to new age. 

This is what I would've liked instead: The previous should be included, but depending on which of these that you, through your actions and productions (and quests/curiosities) and everything else you do, should steer you towards a certain culture-type based on your choices as a player. When the time comes to advance the culture, you get to choose not from all cultures, but from those that more closely resembles the way you have played. This could help flesh out the neolithic age as well. For instance as a neolithic tribe you are nomad's, when you get enough food you get a new unit, do you then split these up, so you can explore further (more explored map --> more exploration points -->choice of expansion culture and/or science culture (curious minds). Or, do you keep the units together in a larger band? Stronger together - less exploration, but stronger force with more battles won/ransacking --> militaristic culture. For influence culture, a "settled" (outpost) tribe could get more influence through [Cave paintings] as an action, for example if that was introduced and so on. Merchant culture could be actual when [Fishing] at special fishing spots at either rivers or coastlines. These are only wild ideas that I am coming up with as I am writing. But basically this, the culture that evolves should be more based on the players choices not a free for all as it is now. And like someone else said in another thread, I would love it if each Era by itself felt almost like a full game. Perhaps an average of about 70-100 turns to reach next era, to get immersed in the one you are currently in. Then I can live with the cultural trasitioning as it is now, without major revamps. Just make each age longer. More different units in Neolithic--> Hunters, goes on hunting expeditions for weeks High risk/High reward ventures. Gatherers stay and gather food, Fishers and so on. What I haven't seen in any 4X game, and still remains to be seen, is the importance of water, not just as commerce, food production and such. But for survival, fresh water. Without access to fresh water no community would exist, which is also why the first major civilisations of the world evolved around major fresh water sources. Shouldn't be able to settle or build a city in a region with no access to fresh water. Which later technologically could be built through Wells, Aqueducts and so on. But without those technologies you'd first have to settle close to a an already existing fresh water source. The most important resource of all.

Ok, sorry, so this became much longer than I first thought, but it just kept coming as I was writing. Just some thoughts :)
