Great videos! I definitely liked hearing the other side of the games.
I liked the mid-game explanations here but I guess the endings were already spoiled for me, haha.
Game 1 - the Fishing Village was mostly in the event that I had some time to pick up a Nobles, but when I had the opportunity Gold felt like the better buy.
Game 2, I think your plan was a bit better than mine with the Smithies, but I think you greened a bit early, which let me take the lead in Provinces.
I definitely made some mistakes in game 3 - I for some reason thought Talismans let me double up on Islands; I think Fool's Gold also was the right choice there. I also played a bit quick and misplayed a couple buys, as WW rightly pointed out in the Youtube comments, thinking that $5 would only get me a Duchy when I had a bridge in play.
Game 4 was a bit frustrating, I had 5 curses and still all 3 estates by turn 8 despite the same opening and two Salvagers. I blame bad luck as you mention but I feel it's deserved! This one seemed decided by turn 5.
Game 5, you pretty much explained my strategy correctly. I Remade the Native Village because it had a Province and nothing else on it and I would much rather a silver at that point. I was also making a point of avoiding Harems when there were other options to mitigate the Smuggler risk.
The bonus game was definitely decided by the trader and that huge influx of Silver. I was hoping to win the split on Silk Roads by starting first but you nabbed the same number as me, and had the better endgame with Trader. Well chosen.
All in all, I had fun and definitely learned some things! If you or anyone else has comments on my play, I'm happy to hear it.
