@slyflourish My most used accessory is a Pathfinder magnetic Combat Pad I bought back in 2011. Little magnets I can write on with wet erase markers, then shuffle around to make the initiative, plus space to scribble with wet-erase to track hp and stuff.
Fantastic tool.
@Azzu @copacetic I think Cairn and other Into the Odd offshoots (Into the Odd, Electric Bastionland, Mythic Bastionland) would fit.
(But Mearls' take on it almost reads more as an adventure design than game design... Like I could write a 5e or even 4e D&D dungeon with the bullet points, and then just include stat blocks in an appendix to pull up when necessary...)
