Well, that could be it. I push hammers in combination with food. In my last game i placed buildings pretty thoughtfull. Still didn't make it.
Let's try again! I usually strart counting in exploration age. Maybe start counting in antiquity helps.
You mention playing tall. I come from Civ 5 where playing tall was a pretty good way to win. Maybe that's also the case in Civ 7?
If tall is viable, then it’s more of a result of the recent patch.
Either way, wide/tall has never been a big factor in completing the Exploration Science path, so your issue must still lie somewhere else.
Here’s a checklist:
1. Ensure proper adjacency bonuses:
- Science and Production buildings go together on tiles with at least 2 adjacent resources.
- Culture and Happiness go together on tiles with at least 1 adjacent mountain or Natural Wonder. Ideally 2 mountains/Nat Wonders, but I understand it’s less of a guarantee.
- Gold and Food buildings (NOT warehouses) go together on tiles with lots of adjacent coast and navigable rivers.
- DO NOT mix in warehouse buildings, isolate them somewhere else into their own quarter. Adjacencies don’t matter for them.
- For remaining adjacent tiles that are not resources/mountains/water - build wonders there. All wonders give +1 adjacency to the neighboring quarters.
2.
Overbuild obsolete buildings. This hasn’t been emphasized enough, but I hope you’re not keeping those Libraries and Amphitheaters around in Exploration. Except for warehouse and unique buldings, all other buildings lose their adjacency benefits upon age transition - so they are essentially dead weight. Also, they no longer count as Quarters - so even if you manage to get to 40+ with a University+Library tile, it will not count towards the goal. Find those obsolete Antiquity buildings and replace ASAP. Assuming you were already placing them with proper adjacencies in Antiquity, your Exploration buildings will benefit from these same locations as well. The only caveat is that some resources disappear upon age transition, so you might have to find a new location for Science/Production.
3. Place specialists into high-adjacency quarters.
4. Leverage Policy Cards and City State bonuses. Anything that says “+X on ___ buildings” will contribute to the goal.
5. The ultimate cheesy strat - Machu Picchu. Settle somewhere where you can surround a Tropical Mountain with districts, rush and build Macchi Picchu, congratulations you won.
