My biggest complaint (and the reason it's a 4-star and not a 5-star) is that Renlock comes off from the backstory and the premise as this very friendly guy, who clearly is supposed to care about these crewmates (they are the only four of his entire crew that he decides to set up for life, after all) but he makes them fight a giant skeleton to the death? I mean, that thing very nearly TPK'ed us and it didn't even roll all that well. It strains credulity to be sure.
However, at the end of the day, it wasn't enough to ruin the story or our fun.
