Necessary expansion for an amazing board game, which everyone who plays board games should definitely have. Amazing even for children aged 7-8 and above, I would say.

Overall, we have played it countless times, if the base game gets a 6/10, this definitely gets a 7.5/10 or even 8. If you have a group of people who enjoy strategic thinking, it's worth it (it's a strategy game, not for young children). If the group is not into thinking or gets bored easily, don't bother getting it... opt for something simpler with cards. You also need the base game to play! Also, if you have the expansion for 6 players, you can't combine it because there are extra pieces needed for two more players. (there are specific expansions for 6 players for each different expansion... you need to have money to spend). The game will last 2.30-4 hours, it's very entertaining, it increases the strategic options compared to the classic game, the possibilities of direct conflicts between players, and it's more unpredictable as cities can be demolished and roads can be removed.

3/5 because:
If you play this expansion after the base game, it doesn't make any sense. I really regret playing it. It may be the best board game I have ever played, but it has countless rules and lasts at least 1 hour and 30 minutes. Most people in my group get bored learning so many rules and playing for such a long time. It's only for hardcore fans. It takes about 15 minutes to set up and another 15 to clean up, with a gameplay duration of 1 hour and 30 minutes. The first time we played it took us 3 hours and 30 minutes because we spent 1 hour learning the rules.

I expanded! After this simple Katana, it no longer makes any sense. The expansion turns the game into a long affair, but it increases the intrigue and the possibility of vertical reversals. Excellent in its genre.

Wonderful game! The expansion takes it to another level! It also tests your relationships with your teammates... friendships will be judged with this game, but it's worth it!
It's complex and requires you to think about many things at once, but that's what sets it apart! I recommend it to those who truly enjoy board games

Incredible expansion! It adds a lot of atmosphere to the game. Of course, to reduce some of the family arguments, I removed some of the yellow and blue development cards!

I have it for about 4 months, it's an awesome expansion that makes the game much more interesting with many extra abilities and twists. As for the duration, if all players know it, the time is reduced by about double the normal game. The interest remains throughout the duration for all players!
