I ran the game Friday night and it was a smashing success. The Goblin Hulk is perfect for dungeon World as it fits with the system's 'anything can happen' mentality. Highlights include:
Guys next to us (playing palladium robotech) stepping away from their game to ask "did you say a minute ago there was a zombie dolphin pinned to a bar?" Me: "Yeah, with a harpoon." To which they replied 'you still got any open seats?" Sadly I did not but I did give them the rppr site address.
PC accidentally turning another pc's rapier into a sentient rapier which I immediately rp'd as Sparkles.
PCs got sidetracked from their escape from the prison deck in the crew deck by joining pit fights for gold.
PC playing the princess bought their battle unicorn back from pontifex (who was onboard for a unicorn auction) in exchange for the bones of the princess's dead subjects.
PCs killed the mage on the orlop deck in a fight after the mage refused to bargain with one of the magic users in the group and said PC through a dagger at the mage.
I began describing bones of the elder dragon in the side of the ship as a result of the dragon crashing into the ship and the corpse getting incorporated into the hull. A few players had this look of 'what is this madness? Who wrote this?!"
All in all, amazing. I will be running it again next con.
