Very fun take on the theme, and well-executed, too! I got the revealer early, but didn't actually figure out where the theme answers themselves were until I'd finished; they were integrated into the grid very smoothly. Who can forget those classic video games like ROCANOMIA and ROMPRAMBLE?
Favorite non-theme clues were the mirroring of 4D4DNamesake of a NYC stadium [and anagram of 35A][----]
and 35A35ANamesake of a NYC stadium [and anagram of 4D][----]
, and it's always fun to get a few bonus space-themed entries with 30A30AElliptical path around a celestial body[-----]
and 34A34AMartians or Jovians, e.g.[---]
