No. There cannot be two number war threads active on the forum. The decision was made by the moderation team when the 4th number war thread was created. May I remind you of the forum guidelines that appear to have been forgotten in the discussion to recreate rules for the number war thread:
Forum Guideline 2.2j: Roleplay, e.g. acting as a Kerbal, creating fictional organizational hierarchy amongst users and/or interactions of fictitious entities of an oppositional nature;
Forum Guidleline 2.2q: Reposting closed or removed content without moderator consent.
While we do understand the desire to create rules for this game that will allow the game to become more fun and less problematic, as moderators, we are bound to enforce the forum guidelines in the forum games section just as we enforce them anywhere else on the forum. Creating teams, sides, maps, and all comes really close - TOO CLOSE - to role playing to the guide lines. This was the very reason that role playing is not allowed on the forum is because all it does is create ill-will on the forum that often spills out into other areas beyond the thread where it starts. I was not a moderator in the early days of the forum (2012 - before the Great Forum Purge of 2012) but I was there and can tell you how bad it was.
If this thread continues to go down this path, there will be no further option available to the moderation staff but to lock this thread and any additional threads created to continue the number war legacy. If one ventures back into memory lane and looks at the first Great Number War thread, this is exactly the reason it and the Second Great Number War threads were shut down. We simply cannot allow this thread to go down the same path.
The condensed version:
Do not create another number war thread. It will be immediately locked and the forum user creating such a thread may find themselves receiving moderation action for violating a forum guideline as mentioned above.
Do not turn this thread into a role playing thread. It's starting to turn suspiciously close to that now. If the trend continues, this thread will be locked.
Please do return to playing the game rather than mutating it into something that violates the forum guidelines.
