My idea for today was to say Walt Disney was to controll again his company after being unfrozen and reanimated thanks a new ultradvanced technology, the "medbeds".
Other idea was to tell WotC was going to publish a Fortnite: Save the World RPG d20, and this would enjoy a digital version next to Battle Royal, StW and Creative Mode. And Tas the kender could be hired as nPC bodyguard.
And WotC was going to produce a new actual-play show, with Japanese aspirant-idols using a virtual-tabletop. Wouldn't be it very kawai?
Time ago my prank was Paizo was to publish a new spin-off, Cryptfinder, a mixture of gothic horror, planetary romance and pulp fiction about the exploration and repopulation within a Dyson sphere that suffered a zombie apocalypse time ago.
The way to make this joke hilarious would be in June if they announce that Spelljammer is coming in the fall. And then a lot of feigned "we teased it in April, why didn't anyone take us seriously?" acting around it.
