Here is a list of the game variations in the experimental series and their codes. Any appropriate ideas posted will be added (keep in mind that these must be able to be implemented without the Devs programming anything extra!

001 - Public chat only
002 - Subs are only allowed to be launched between the bearings of X degrees and Y degrees
003 - You can only attack outposts outside of your sonar range
004 - Target Np is X (Once someone reaches X there can be no more changes to the game, just let the ranking on the info panel stay the same)
005 - Everyone starts with 1 Mine (Everyone must have sent 13 drillers from each outpost to the outpost of their queen and built a mine before any other launches are made)
006 - Specialist hires are random (You must state the sequence of hire options that you will choose (1, 2, or 3) in the public chat before the game starts)
007 - You must fund everyone you can at all times
008 - You must resign after X days of being in first place and having more than Y Np if you don't win
009 - You must gift a sub of at least X drillers to the player in last place every day
010 - When a player is eliminated you cannot launch subs at the active players until the eliminated person does not own any more outposts.
011 - Actual preset teams. All your subs going towards your team member's outpost must become a gift immediately.
012 - There must be a minimum of X drillers on all subs at the time of launch
013 - ...Suggest more ideas below!

Thank you for compiling this post!

Setting a minimum number of drillers sent on an attacking sub? Ex. there has to be at least 30 drillers per sub attacking, no small driller sub launches
