I've been enjoying how Brennan seems to be using the limited format of the EXU series to explore game balance scenarios that are interesting but untenable for the average long-term campaign.
What if you faced a CR 40 challenge but everyone at the table is literally a god? What if you have wildly unbalanced abilities, so you can deal 300 damage easily but you only have a normal set of hit points? What can you do if you're guaranteed to pass almost any skill check? What if the table isn't even level 1 yet, but they have access to artifacts of enormous power meant for level 15 characters? How do you play tactics for these challenges? How does the DM plan for them?
Notable interesting examples include the DM's failure to quite plan for what a 20th-level wizard can do, meaning that the intended imbalance of the "unshackling the god's power" scenario was far more short-lived than intended. On the converse, the players have had some pretty fun tactics: see Ashley rolling a 60 to persuade a construct to abandon its programming, or Matt looking at his character sheet and smartly deciding his artifact-level siege weapon would be much better applied using the terrain to cause damage for him, rather than walking up to the enemies and whacking them with it.
