The musical accompaniment of the bards in the second PAX game in general was good, but the look of shock on Jerry and Mike's faces as the bards joined in on Wil's Oath of Enmity was awesome.
Scott Kurtz remarked of that game "We are spoiled for all future D&D games" referencing the Minstrels (Paul and Storm).
This is the only way to describe the climax of the 2013 PAX session. What's the final secret at the end of the dungeon? A magic-powered mecha that operates like something straight out of Pacific Rim, which Acquisitions Inc. is tasked with using to fight the goddamn tarrasque. The finale of that fight bears special mention: Omin, in control of one of the legs, hits the tarrasque with a Groin Attack and it keels over dead.
