Having read through Doom Cave of the Crystal Skulled Children, I have two things to say:
1. I'm glad it was free
2. Better Book Title: Push Button to Ruin Character and/or Campaign.
I know a few people in Blogaria who would say that statement #2 applies to all Raggi's work, but my impression of Doom Cave is that the character-fuckery is a lot more arbitrary. Normally I enjoy LotFP stuff, but this one leaves me cold. I enjoyed Better Than Any Man far, far more.
Also, regarding the seemingly recent (to me, anyway) trend of "Fuck up your entire campaign world" traps in Raggi modules, I state this: Players losing characters over foolish decisions or bad luck are part and parcel to the game. Me losing my campaign world over the players' foolish decisions or bad luck? No, thanks.
...now, don't get me wrong. If my players orchestrate an epic success or epic fuckup that destroys the world, fair game.... but destroying the world because they messed with a widget in a dungeon and got a shitty roll? Homie don't play that.
*I don't follow baseball, or any sport for that matter, so I'm not even 100% sure what this analogy means.
