Windows version is $6.98 new and $5.50 used.
Mac version is $37.95 new and $48.09 used.
(That's not a typo. There is currently one used copy of Mac NWN on Amazon and the seller wants more than a new copy.)
I was expecting a Windows/Mac combo like I got for Diablo II. Guess that's pretty much a Blizzard-only thing, eh?
Here's hoping the Mac games market really benefits from the move to Intel processors! (And I'm not talking what Cedega's done for GNU/Linux, either.)
Hilariously, I recently bought Neverwinter Nights FUCKING AGAIN because of this. Also I couldn't find my Mac copies serial # or I would have just juarezed a copy of the x86 version.
I also realized I've bought every game Bioware has ever made except MDK2--but since I've bought NWN TWICE I think I have that covered.
