that mistified me a bit when i used steam at home over dial up with there being a no map folder , but yet i was still able to play online and stuff , i just copied wads i had from 1.5 that 1.6 did not have and that worked fine , i also moved maps like fy_iceworld & such , after it dled a map , then it created a maps folder
Why the hell does steam have to be so darn Stupid
