The Grigori, summoned normally, are *more* expensive than demon lords, with the same research and casting requirements... but at least you don't have to worry about having them poached off you.

Except by wishes.

Maybe wishing for unique creatures should be banned (or produce only an imitation, which may be an imperfect copy in some way and doesn't take away the genuine article from whoever is employing it), and you can still wish for pretender chassis and other non-uniques?

But I have to admit I haven't been in any MP games long enough for wish to come into play, so maybe it's not really a big deal whether it eliminates national barriers and allows summoning chayots cheaper than their regular cost etc.
