The only regulation that everyone has always agreed to was no objectives and kill count won you the game. Either the game went to the time limit or a team quit early after getting fvcked for 10 minutes...
Anything else: the only thing I could see being a variable would be alts vs alts or mains vs mains. You can't really police people using passive AA buffs or somtimes even major ones, and using the trust code would not work because AoC players are amongst some of the shadiest peopleI ever gamed with.
So, other than agreeing to alts or mains vs. whatever and no objectives, you can't really be sure everyone is abiding by a pre-determined ruleset.
