mainly strategy game

If you understand the rules of the game once (take some), it is a very challenging game. A luck factor, there is little (except the 6 cards that have to be taken).
If the game is played in pairs, it is like a chess game. You have to like.
I find it annoying that one after every train by having something built, can be an all taken away again.
Games like glory, Leonardo, pandemic, Medicus, Puerto Rico, etc. I like better.
