game 1:
You have to play engine because if you give your opponent all of the cards in all of the cool piles it's just too much. Also in the engine-vs-BM match the engine can easily play around 3-piling long enough to get some big bridge turns going. However, it isn't a very strong engine without trashing and very mediocre draw. When both players go for it, it will certainly end in a 3 pile before anyone ever really gets his deck going. With draw being the main problem, and the best draw card being non-terminal, fishing village isn't near as good as it can be. I'd get "regular" (farming) villages on $4 for sure. Some Fishing Villages is fine but they're not great. Much worse is your outpost this early. That certainly should be Stables; that's a very important card to have. You'd rather have one double bridge turn then two half-baked turns with 1 bridge each.
game 2:
You could go more engine-y here, you could also play BM-ish. No +buy is certainly no reason to skip the engine, workshop on throne room is easily enough gains to make that work. But there is no draw, barely any trashing and also not an impressively mean attack. If you go BM-ish though you should really go Monument-BM. That's much much stronger then island-BM.
Only when your opponent is trying to get his "engine" to a consistent deck by using island for pseudo-trash, you can decide to deny him some islands.
