So how are Arena Rps different? Do they rely on a mechanics system or something?

Well, Arena RPs just need someone to keep track of things (weapons used, health, power ups, etc.). It could be easily be removed as there isn't much people, who are regularly active on that subforum.

EDIT: I am such there is a system of something; but, they are uncommon in the arena subforum.
EDIT: It isn't like Tabletop RPs, where you always need some mechanics system with you (dice generators, etc.).
