i had the desire recently to play diablo2/LOD again and was pleasantly surprised that the latest patches from blizzard allow you to play the game without cds. simply copy the .mpq files from the diablo2 play cd (if needed) and the LOD cd to the diablo2 folder.

one other thing is that the game can be ran in windowed mode by putting a “-w” at the end of the d2 shortcut.
