I don't think selling stuff is against AUP so hopefully this should be ok. I have recently went out and bought Nevewinter Nights 2, after finding playing the original great fun. Unfortunately, even though my PC met minimum requirements, it ran really slow and all of the graphics had to be turned right down which made it look, well s***.
I have only used it twice and there are no scratches on the disk. The game manual has a slight crinkle in it, but it was like that when I bought it.
If anyone's interested in buying it off me then feel free to reply with any questions etc. I'll probably sell it for around £15. UK only.
Thanks
P.S, I'd recommend that you have at least 1GB RAM, and a GeForce 7800 to get some decent graphics.
