Finally, I have managed to bodge together a plan for my Winter Set buildings that I won on beta.
For a 6x5 shape requiring quite a lot of road connection, I can get 18 goods, 5 FP, medals (quite a lot of), attack boost, coins, supply, happiness.
Even allowing for the road connectiions, that's better than a Terrace Farm (5FP
or 20 goods) and
arguably better than a host of SoKs, since although they would give more FP and about the same coin, they would 't give the goods etc..
The problem is that they are almost all previous-age, so the goods are old ones and everything but the FP is lower than it would be if only I had known I would have to advance an age to complete the Winter Event. And at NINE buldings, there isn't a hope in hell I will get enough one-up kits. So maybe I am talking myself out of using them after all
