We played a match of Clank: Catacombs with 3 players.
One player was new to Catacombs itself but knew the normal Clank. The dungeon layout this time turned out a bit more tricky and there were few easy escape routes. The new player panicked a bit and decided to grab the lowest value artefact and run for it. He only made it out with 60 points. Final score was 121, 111, 60.
I really like how each game feels much more different with Catacombs, the layout of the dungeon being discovered throughout the game creates a lot of tension. If you love Clank but know the map inside out by now, Catacombs is the answer.
Whenever showing someone Clank, I usually first play a game of Dominion to show Deckbuilding, then we play a game of normal Clank. The next time they come, Catacombs is on the table.
