Having played GMT's Twilight Struggle I was eager to get this game. It's a card driven game much like Twilight Struggle but that's probably were the similarity largely ends. In Twilight Struggle, both sides operate identically in that they can do the same actions. Not in Labyrinth. Both sides operate completely different and don't have any actions that are similar. It is a harder game than Twilight Struggle and will probably take a few games to get everything down. In our game the Jihadists (me) ended up winning the game.
The game has 4 different scenarios that determine how everything is set up. Each side has 2-3 ways in which they can instantly win. Otherwise the game ends when the players go through the card deck. Before the game starts the players can determine how many times they actually want to go through the deck: 1, 2 or 3 times. As this was our initial game, we plodded through it and we only went through the deck once. As a result it took us about 3 1/2 hours. Experienced players going through the deck 3 times would still take a good afternoon to play. And as with all recent GMT games the production quality is top notch. Hopefully I can in a few more games this Xmas season.
