I greatly anticipated this module coming out and, when I told my group that we were going to play it, they were extremely excited too. Who doesn't want to build and fight killer robots in a fun, prank-filled environment?
In my opinion, the best part of the module is the bot combat, and you can easily lift that part and put it in any other campaign. There are a lot of options, and you can be creative. Setting up the arena is also a lot of fun, and, since the DM has a lot of freedom, you can easily increase or decrease the difficulty.
I overall liked the setting of the Communion of Laughter and how it tied into Garl Glittergold, but I think it would have been best to develop that a little further -- maybe have a table of pranks or different machines the party could interact with. However, keeping it deliberately vague gave me as a DM and my players the freedom to explore our own humor and be creative; my personal preference is just having more guidance.
This module is 150% worth purchasing and playing, not least because the proceeds go towards Extra Life. Give it a shot -- you'll love it!
