Unfortunately, this mission supplement does not live up to the high standards of past Paranoia adventures. In this short module, the players are sent on a mission Outdoors in a slow-moving vehicle. The biggest weakness of the book is simply the lack of content: literally, nothing happens between the prologue and the finale. There are no challenges or encounters for the players to interact with along their journey, nor are there interesting devices in the vehicle for them to challenge each other with. Additionally, despite the fun title, the adventure is not a reference to The Princess Bride.
Overall, "Robots of Unusual Size" is strictly inferior to the missions from the Mission Book included with the Paranoia set, which are fantastic. For game masters who want a fun mission that takes players to the Outdoors, try to get a copy of "A Question of Ballast", which was included in the old Paranoia Flashbacks Redux Redux book. That mission takes the players in a hot air balloon in a quest to disable nuclear landmines. Along the way, they are forced to deal with a malfunctioning heater, and must choose what (or who!) to throw off of the balloon.
