 # Introduction
 While most titles from Blizzard receive years of love and support, Diablo stayed in the shadows. Abandoned in favour of a sequel, it remained full of bugs and unfinished potential. The game was last patched in 2001 before being discontinued altogether, a problem I wanted to fix. I played Diablo extensively as a teenager, but as time passed it became difficult to run the game on newer hardware. The lack of many improvements found in the sequel also kept it from ageing well. At first the game appeared to be a lost cause, but thankfully a little oversight in 1997 made it not so.
