I'm new to this, but I'm wondering if it is still too early for this specific a rule. OTOH, this way of getting points could be revised when new ways are devised. It also seems like as things stand, we will all be going near each other and getting the same number of points. Is there a mechanism for moving units?
You are right - the rule as currently devised makes best play us just all huddling up in the center (yes, there is a way to move units). Something to remember, though, is that the rules are constantly changing (seriously though, I mean it) and this exact ruleset will cease to exist at the end of the next turn (most likely).
Based on this, if this rule passes, I would use my turn to place rivers or mountains or some sort of barrier on the map to make achieving this a little more difficult.
What I like about this rule the most is, we get to earn points again! I hated the only way to earn points disappearing without a replacement and would have voted against it in the strongest terms, but I wasn't in the game yet.
