I used to own the original NWN as well as Gold and Hotu, but have since lost them in a move. So when I saw it on GoG I was very happy to get it for $9.99(or $5.99 cant remember which). I run this on both a Windows 7 system(3gb Core 2 Duo 4gb ddr2 and 550ti) AND a Windows 8 newer laptop(2.6 quad core Intel HD4000 graphics and 6gb ddr3) and they run great. I saw a few reviews saying it wouldn't work on 7 but it does for me. Small problems I am having though are through character creation. Wizard spells I pick are changed when the prelude starts up, and for some reason I'm not seeing the Aurora Toolset(Is it in GoG's version?). Still though for the price, it is VERY playable still. I'm okay with the small glitches I guess but would like a fix.
