Played a four player game today with a strategy I kinda stumbled into that I felt was way too powerful...
I obtained Construction: " I demand you transfer two cards from your hand to my hand, then draw a 2!
If you are the only player with five top cards, claim the Empire achievement."
Which in a 2-player game can be a good card, but in a 4-player is dominant. I played it a few times and received 5-6 cards each time. From that I obtained cards of multiple colors and Currency: "You may return any number of cards from your hand. If you do, draw and score a 2 for every different value of card you returned."
The last construction play I was able to obtain the empire achievement and playing Currency twice allowed me to score ~ 40 points and a whole lotta cards--because Engineering not only steals cards from other players, but has them draw a 2--or a higher card if the 2 card pile is gone--as a result I was scoring 1-6 cards each time I played it, generally 1 of each 2-5 and two 6s. From that I was also able to obtain the Monument achievement. By that point the draw had reach about 7 and on my next turn I drew and melded a 7 and the next I achieved 4 & 5, but could have achieved 6 & 7 for the win... as you only need 4 achievements to end the game in 4 player.
Perhaps there was a way for players to block me--having more castles would have, but I had about 6 at that time and in four player all the castles were spread pretty thin--but my opponents couldn't see anything. We thought it was extremely strong. Perhaps too strong.
Thoughts?
