Game 1 is an apothecary game all the way. I would wager that an Apothecary/FV (that's Farming, not Fishing) engine could get 6 Provinces in 15 turns. Even when greening, the FV's will skip over dead VP cards. Probably open Potion/Shanty Town and prioritize buying Apothecary>Farming Village>Silver(just get 1)>Village>Copper.
Edit: And I believe I just found a game where Thief is an optimal strategy! With no +Buy, the Apothecary engine player can not replenish lost Copper without also including Thief. The winner of this game will be the player who uses Thief most efficiently to control the distribution of Treasure Cards!
