Functionally, it doesn't matter per se if we can call from "outside" the editor or "inside" the editor.  If "inside" (the classic ~ prompt), it would be nice to have a lot of robustness, however (e.g. mathematical functions, data structures, etc.).  The advantage to externally-facing function calls (dare I call it an "API"?) is that modders could use Python, PERL, C++, or plain-ole' shell scripting to develop algorithms for randomization.

I'm sure the in-game map randomizer will be very good - GalCiv2's AI alone shows a strong skillset in algorithms - but modders may be able to do more: rain-shadow effects for mountains, accounting for ocean currents, etc.

This request is definitely more for the smaller, geekier crowd than for mainstream players, and possibly even mainstream modders. 

Sounds good. I'd probably never use it, but considering that a lot of the people who play EWOM are probably going to be computer geeks anyway, it seems like it would be worth Stardock's time.

I'll happily accept Karma, especially since it increases my chances of getting into the Alpha. 

But cookies are good too, especially those snickerdoodles that are just a little bit chewy on the inside, yet slightly crispy on the outside...but I digress.
