Pietato
Platonic Perfection
It may not mean much in this thread but at least, it my opinion, should let stuff like Chocolate Hills outlast mostly inconsequential stuff like Giant's Causeway (which got nerfed to expire its bonus when a unit gets promoted, so you have to travel back to refresh it... no thanks).
That is untrue, mate. Spear of Firion does not expire, and persists through upgrades, promotions and corp/army mergers. Upgraded a unit with it 15 minutes ago, who gained it as a Swordsmen, and is now a Mech Infantry (3 upgrades), and it persisted through it all (like all natural wonder buffs do, now). I am sure someone has a link to when they fixed it.
Chocolate Hills gives uncompetitive yields these days, due to the massive power creep. Good for a national park and the Maori, though not enough to beat the others on this list.
