HermitCraft tag was started by Grian, and was small at first but has now started escalating to the point of going AFK whenever the tagged person is around.
Hardcore Hermit fans who have been keeping up with who has been tagged, please write here.
The latest and first game evolution has already happened, Mumbo deciding that the tag does not have to stay it your inventory. A new game rulebook is yet to be written but I'm sure it will happen soon. Fans are also predicting an evolution by Iskall, being that you can kill the tagee.
The most hilarious one has been Grian wasting tons of fireworks attempting to tag CubFan and failing due to Cub teleporting away quickly before he got tagged.
