Yeah I noticed after that there are <$4 actions makes it much more difficult, making vineyards a harder investment. With that said, I believe that Inn can help organize large turns in order to spam actions on those turns. With the Mint there as well, you can essentially eliminate all your coppers/silvers on one of those mega turns.
I love my vineyard engines so I may be biased, but I think you can reach 30 actions faster than the opponent reaching 8 colonies.
You need to get 30 actions AND all 8 vineyards though.... not sure how that will work.
Am I the only crazy one? =(
For the first... 8-9 turns, I would purchase rabbles/inn/bridges/silvers/...
2. Buy an Inn at the end of a shuffle to build a megaturn (this is probably a flimsy proposition, but its what i thought) in order to buy a mint and remove all treasure (on the following turn), probably keep a silver but all would be gone ideally.
3. I should be able at this point to purchase more Inns/Bridges if the megaturn went correctly...
4. With Bridges and Inns play, I should be able to gain 3-4 actions a turn.
Again this is probably a flimsy idea but i would rely on this than FG because its more fun. Even if that mega turn goes awry, its not as harmful to this engine because Inn acts as a mini warehouse.
