short summary:very complex game that takes a long time to set up, and understand the rules. set aside a lot of time for your first playthrough. but it goes quicker once you get a handle on it, and builds to a big splashy climax that everyone can contribute to both individually and collaboratively.Longer review:Just got this game and played once through with a 12/15 yo, and both are familiar with complex tabletops. We played it (and pretty easily beat it) with both of the two nerfing rules in play, as we were learning the game; next time I'll play with just one of the nerfs. It still took about 4 hours to play, after setup, and that only got us through about 1/2 of each of the game timer decks before we won outright. (I wouldn't expect a game that consumed those decks to necessarily take 8 hours--it's just the learning curve).The below notes are feedback from just the first play through. I really think it'll get much much easier with experience.Cons:-it took about 90 minutes to follow the setup instructions. I'd expect subsequent games to be closer to 30 mins now that we understand the nomenclature of the pieces. There's still somethings that will take time, like deck building.-it needs a good size table. There are lots of cards for the players to manage individually that cycle in and out of play.-the rules are daunting. I spent 2 hours reading them and grokking them, and then another 30-45 mins teaching the kids, and it took about two turns before we really all got.
