mrkgnao: I expect it's a temporary "setback" and will be restored to its "full and glorious" regional pricing once GOG notices the extant vestiges of the "bug".
IAmSinistar: I'm not so sure, since all the M&B titles are priced that way. I'd like to think that GOG actually has an agreement with the publishers on this one to offer the same price everywhere (again, except for the "if it's not cheap enough we steal it" clientele).
I feel okay buying the M&B games now that the price is basically fair for everyone, and I hope it remains that way. I'll even pick up the Vikings pre-order in gratitude to GOG.
And it's "fixed".
