NWN2 is now $35 at Amazon.com. I think that's with free shipping, too. I'm really enjoying this game, but it's extremely, extremely easy, to the point that it's not really a game.. but an interactive novel.
Then again, if you have no understanding of the D&D rules whatsoever, don't read the manual or anything, then this game might pose some sort of challenge. Hehe. If you click the link below to make your purchase, I get like a few cents in commission. So yeah, gimme a few cents!
Me and Dogar (online friend) hope to tweak the game's difficulty using the Toolset. If we can do that, I think this game would be an instant classic.
