Is it me or few golden age are really worth it compaired to most 2 cost legacies?... For example:
- Wondrous Heritage (2 points): Wonders you control get +1 Culture and +1 Happiness.
- Wonders of the Ancient World Golden Age (2 points): Amphitheaters becomes Golden Age Amphitheaters (They retain their base yields, adjacency bonuses, and effects in the next age).
You will have at most 2, maybe 3 amphitheaters by the end of antiquity. But if you have the golden age, that means you have 8 wonders... So choosing wondruous heritage get you nearly as much culture (not linked to a building, that can therefore be overbuilt) and even happiness. So the golden age does not give you that much benefit, especially since exploration age give you more yields that an amphitheatre... Same thing for science legacies...
Same for the military path:
- Fealty (2 points): +2 Settlement Limit.
- Pax Imperatoria Golden Age (2 points): Gain an Infantry unit in every settlement you conquered last age. Total Units: X.
Fealty if way better than some measly units... Not only most of your units carry over (provided enough commander, but still), but settlement points are invaluable in exploration age where you have to grab distant lands as soon as possible, and mainland conquests are worthless...
For economic, you can count at 200-250 gold per city you retain. Not cheap, but if you had enough trade routes it gets prety even...
For modern legacies it is roughly the same (except for the economic golden age, since 2 pops in the distant lands is rather good)... So I really can't see the appeal of golden ages...
