De-lurking to say that I'm enjoying this so far and am looking forward to more. Combining OOTP and SC4 is something I've wanted to do for a while (in fact, it was
a thread on this board that inspired me to start playing SC4 in the first place), but I'm very impatient with it - I have a severe case of new-map fever. So it's good to see someone's managing to do it.
When you say you might upload your region file, do you mean just the map or the entire developed region? If the latter, I'd love to see it and take a trip around. Uploads of developed regions seem to be very rare (I've only ever seen one anywhere I've looked).
