NWN:EE will be sold by gog.com in a few days time. NWN will be included with NWN:EE purchases after October 11th, 2018, but NWN will no longer be sold separately after October 11th so if you want a copy of NWN without having to purchase NWN:EE go get it before the 11th!
Everyone - this means we will see MORE new players too!
