I've successfully removed all traces of the challenge system from my arcade to save on a couple of queries here and there since my users weren't using it anyway..
I'm mainly posting this to see if anyone would be interested in me documenting the edits required to do this themselves (it's quite extensive).?
I'm asking if anyone wants me to document this as a mod so that they too can remove the challenge system from their v3arcade installation, as I've already done this successfully on Gamers Euphoria.
