Sir D - responses like that don't really help inform or rationalise the reasoning process do they? [img]tongue.gif[/img]
I'd pay $10 AUS for it brand new, definitely. All depends how much a fan you are of AD&D products I suppose, which would be the deciding factor in the end for how much you'd be willing to pay.
Bargain bins might have it cheaper, obviously.
If you're in doubt, be sure to check out some of the threads on the game here. I know guys like Lucern, Betelgeuse and a few other turn based fans had fun with it...just be sure to have the latest patches.
I'm yet to find it locally where I live at a cheap price, but as a long term cRPG AD&D freak, I'd try it out at least, what's a few lousy bucks?
