Got your eye on one of those nations, Zeldor?
I'd prefer to stay with the original criteria. Makes for a faster game with one less water nation (advantages in my opinion). Also, if you are including LA Caelum in that count ... well, I don't think any version of Caelum is weak.
But I mainly hope we can play with CBM 1.6 as the only mod and not get into a discussion of compensation for the lack of clams.
