Finished my Exploration age last night and semi-accidentally stumbled upon science legacy completion, while waiting for treasure fleets
1. You don’t need to stack buildings of the same type, just look for combinations that give you the best adjacencies. You need good foundational adjacency, because:
2.
Specialists. They give +2 science/culture by default, but they also multiply the adjacency bonuses, thus propelling the yields. You can only place one specialist per district at first, but the limit is increased by 1 with Education and Urban Planning.
3. There are also various techs, civics, policies, and masteries that further increase building or adjacency yields.
4. My personal observations:
- Don't invest specialists in city centers, they don’t count. It’s stated in the description, but I promise you’ll forget amidst all the new info pouring in your face.
- Stack any ageless antiquity buildings or buildings without adjacency potential in their own quarter, and don’t invest specialists into them.
- To anyone who still doesn’t think that UI is bad in this game, I invite you to go for the Exploration science legacy path and make a conscious effort to plan your tiles, as opposed to “big number, plop here I guess”.
