Hello everyone, i didnt seem to see any link to RealmCrafter, its an great and easy 3D mmorpg engine, the price is around $55.

I guess it's still in a relatively eary stage of development, but it's fully possible to make a mmorpg with it.
EDIT: And yeah it has its own scripting language, and the engine is developed in Blitz3D. you find more information on the homepage.
