Well, to be honest, Diablo 1 on PS1 absolutely sucks. I bought it a little while back as another hack and slash for my friend and I. We started it up and after a couple of minutes, we both looked at each other and said it sucks and turned it off.
While I would play the PC version, it would turn into a household nightmare. The PC always has someone on it and if Im gaming on it, I would hear a lot of bitching.
