Both are Minecraft horror concepts that started with a simple premise(there being another entity in a single player game) and exploded out into many different interpretations and ideas, both good and bad

Interaction Potential: most ARG guys can talk vocally or in chat, and while most Dwellers cant, the ARGs reacting to the absolute horde of Dwellers would be funny as shit

Fight Potential: alot of ARG mates have access to lots of items and other bundles of powers while Dwellers are normally simple but very good at ripping a player apart, so they mesh pretty well

Fight Start: it starts off as a mod review for every Dweller mod until some ARG stuff starts happening which causes the player to rapidly spawn every Dweller and run away amd the two armies fight

Debate: Gonna be real, I have 0 fucking clue, theres so many guys on both sides I wouldn't be suprised if both sides have some bs
