Disclaimer: The information listed below is about a game that is still under
development, and so is incomplete and subject to change.
Research works much as before, but each technology has a "Eureka" objective attached to it. This objective is a mini-quest (such as "Meet another Civilization" or "Build a Quarry") that, when completed, will award a research credit worth 50% (!) of the science needed to unlock that tech. You will get this research credit whether or not you are currently researching the technology in question. As with Civ V, there is no tech trading.
The research tree is smaller than in Civ V, because a number of items have been moved to the new Civics tree (see below). Taken together, these two trees have about 118 total, 40 more items than the Civ V tech tree.
“We wanted to make sure your progress in the tech tree was something you had more control over, something where you could push your progress if necessary. So what we’ve done is, for pretty much every technology in the tech tree, we’ve associated a specific activity that’s sort of like a quest. And if you finish that activity, boom, we give you a big credit, about 50% of the science that you need to unlock that particular technology is granted to you. So the tech tree is now set up so that it adjusts itself based on your play style. If you’re playing the game militaristically, all of a sudden the militaristic path through the tree is going to open up and be easy for you. If you’re playing the game building a navy, all of a sudden all of these maritime technologies are going to open up for you. It rewards you for being active in certain parts of the game.” - Ed Beach
Technology Tree
Here is a full version of the tree from the 03-Aug videos. Keep in mind that this is almost certainly not the final version of the tree.
