I was just about write a post on this. Diablo 1 is one of my all time favourite games (I actually like it better than 2), and after seeing his work so far, I was quite impressive. Though it's still only a very very basic alpha with choppy framerate, the guy behind it actually analysed the game structure for academic purposes, and he seemingly knows a lot of what goes in the backstage. Not only because I'm a FLOSS and Diablo lover, but also because the original game has massive compatibility problems, this is one of the FLOSS engine remakes I really want it to succeed.
