For me, it would probably be:

• check if I can read my phone with the cameras
• test out guardian set up
• check hand tracking quality and controller tracking
• wiggle my head to see if it feels different
• check if Ghosts of Tabor is still a slideshow
• check graphics & performance in Zenth, Red Matter, Gorilla Tag, Dungeons of Eternity, beat saber
• check Swordsman VR upper body tracking (and if it’s already there)
• check out some mixed reality games: Demeo, puzzling places, and new mixed reality games
