Yes, back on topic...

I purchased GC1, and used it somewhat, but when Vue7 hit the streets, with the improved terrain editing capability, I slowed down with GC1 use. I just purchased GC2 the other day from Cornucopia, and it is a vast improvement over GC1. The ability to create rivers, lakes, and roads is alone worth the price of admission.

Also, the Vue export/import seems much improved, as the resulting terrains brought into Vue have much more detail, and less low resolution "layer" effects. It's going to take me quite a while to nail all the capability of GC2 down -- actually, I'll probably never get it truly nailed down. GC3 will likely be out before I get highly proficient with GC2.
