Do you ever choose to move capitals, and why?

[Nic@Melbourne]

I try to always move it if it works to a smaller city/town.
-smaller settlement makes use of the boosts from palace better than a big city.
-old capital is out of space for wonders
-like keeping the old capital name

Others can verify, but one tip is to first use gold to make cities you want cities, and THEN select this legacy option. This is because the gold cost to upgrade cities seems to depend on pop and how many cities you have, and is updated dynamically even during that first turn.

Mind blown!! Okay, I take it all back!

Usually the capital potentially has the highest production output, which is most critical to build wonders. When I pushed hard to build them in earlier age, the most of locations for wonders ran out in the original capital. That's one of the reason why I choose to move capital in upcoming age.

Yeah the Palace gives +2 more production per age than a City Hall and +2 resource slots which can be filled with whales or other production resources so it makes sense to have your capital be the one with the most production potential to build wonders and endgame projects.
