i decided to go digital for some reason
it is digital drm free download from http://www.buy3drealms.com
/. The Deal 3D Realms (Apogee Software ltd.) has with Apogee Software LCC. only includes DN3d and DNMP from the duke series. The apogee store is run by REGNOW the shareware arm of Digital River While you can't download anytime like here the game is not as locked down as Steam and is packed with dosbox to allow it to run in 64-bit windows.
and my pc end up screwing up again and can't redownload again.
