I agree that Minor Factions would overcrowd the galaxy map and overwork the staff.
The map as we see it on the screen is rendered in two dimension.
There is in actuality much more space and star systems in a hex that can in a practical manner, be registered here on Chaos. I'm meaning that there are star systems within a faction claimed hex that even they don't know about or said to have discovered. I'm getting to the point as in there is enough space out there for Minors to play out as one of their own systems without having it registered on the map.
Let me explain.
Here is how hex are seen as far as the map is concerned and why it currently should remain Major faction registered.
See...the hexes are limited 2 dimensional surface spaces, as far as registering systems on them.
The above is how we see the sectors (hexes) in our galaxy. They are practical as far as being managed.
Below is how 3-D space in a hex could really look like, or is able to hold countless more stars and systems.
It would be impossible by our standard current gaming format to cram in Personal, Minor and Major Factions star systems and planets in any given hex, as we currently play it in 2-D.And 2-D is practical.
One day, it will be possible to play a truer 3-D map game with everyone or anyone occupying the same hex. Just that this isn't that day, and the map must be maintained in its 2 dimensional format by our staff. And that is a load in itself when borders shift and majors go minor and off the map.
So for now, the only efficient way to play is by the current rules and standards and that is with limited hex occupation. Anything more (as it's pointed out) will overload the staff and then their fun stops. Everyone must keep in mind that staff also enjoy writing, and they make enough sacrifice of their given time on line in keeping the rest of us playing without the same responsibilities and time needed to maintain the current map.
Keep the map game as is....just my 2 credits worth.
