so for the kids on earth c, will they live forever because they’re still god tier? or are the god tier powers cancelled because the game is over? also if the powers don’t cancel, does this mean dave and rose will inevitably outlive karkat and kanaya? thanks!

The god tier powers are still in effect as seen when they go to fight in Caliborn’s Masterpiece. And yes, Dave and Rose will eventually outlive Karkat and Kanaya if they ever get out of the house juju.
