Quality: beautifully finished box with many stable markers and ordinary cards for the heroes. The cubes look fabulous! Is there nothing to complain about but not much to write :)
Fun: I've played a few rounds alone. While this is okay but not amazing. The meeting with 4 people was then already a lot better. Although it does not interact with the other players but it still brings a lot of fun getting to try on to get into the dungeon as the other. Dungeon roll is not particularly nachdenkintensiv but you should already partially recalculate how far one needs to go in order to win still can. In particular, in the last round.
Balance: Some heroes are much stronger than others, and sometimes one can hardly to use his special ability. But that's not necessarily a bad thing, to the last part more.
Replayability: It depends. If one chooses what to play heroes rather mediocre. You try to get one of the strongest heroes to win. What I recommend and we did well in our group, the random drawing of heroes. We have to sound until all heroes by were, but you can easily pull out of every all. One has its variety every readjust and can try out different tactics. Here come the unbalanced hero to use, because if can be a hero whose ability bad acts suddenly exploited to the full, making the same profits a lot more fun. Overall, not a game that you play for hours, but from time to time or when one of the larger board games ended too early a great thing.
Tactics / strategy / happiness: happiness depends. There is much diced. And if the hero draws amn then it goes more in the direction. Strategy and tactics is nevertheless not unimportant. Who does not think already needs an extreme bunch lucky to still win :)
Duration / rules: The game is short. With 4 players that can not play the first time you expect 20 minutes for a full game. In wenigern match shorter. But even with new players, it does not take long to explain the rules. There are 4 overview maps showing the important things again for each player to the short Rulebook.
Conclusion: I can wholeheartedly recommend the game and am happy to note participated Kickstarter project!
