No, I'm arguing about a suddenly implemented 'test-version'. This is the main reason why i hate 'test-versions', because as soon as they are added they can't be removed or changed without a unanimous decision.
Well, the Inca were considered top-tier for deity-picks in vanilla, I'm sure that wasn't because of their non-factor unique unit.
On the topic of yields, I'll just assume that the ones saying food instead of gold will just win out and that's what the polder will add to the village. If it is just gold there is no point arguing about anything because the village would probably not be worth replacing a polder for anyways, even with +6 gold from adjacent polders.
Congratulations, you either have two uniques that both sound really weak and really boring; or you have one unique providing good enough yields and an unfair, uncalled buff to villages

.
Don't get me wrong, I've been pushing for a change in polder requirements since forever, floodplain starts were just way too unfair.
Having them buildable on all freshwater tiles is a nice change and makes the dutch way less RNG dependent, especially since marshes/floodplains/lakes aren't valid startbiases.
I'm not saying that the dutch can't be buffed, in fact no matter how you do this it is probably going to be a buff. I'm saying there is only so much power you can pump into one unique before balance suffers. You can't for example aim to make William stronger than for example Montezuma just because you want more room to have both an interesting tile and an interesting adjacency bonus.
So your one argument is directly copy-pasting my argument...?
This was present in the base-game as well so it's probably some mechanic that I don't understand, but why would there be hammers on the polder?
I can see Food (growing crops) I can see gold (growing cash-crops) I can see culture (Unique, looks cool, inspires art and so on) but where would the production come from?
On the subject of yields, I have another reason why I think the village adjacency bonus needs to be dropped, Polders needs the yields to compete with Imperialism and cathedral buffed farms, and I honestly don't think that would be possible while still adding a possible +6 yields to villages and still being balanced, I just dont.
