Diablo via the PS1 emulator works fantastic last I played through it, so long as you enjoy the warrior. The Rogue might not be bad, but casting blows in the game if you need to target (such as via teleport, most combat spells...) so I gave up trying to run through as the Sorcerer at Diablo since I can hardly get a hit or two in before he kills my golem and then me, and I can't flee since I can't teleport fast enough.
I haven't tried Baldur's Gate, thanks SONY for the suggestion as I'll have to look into it.
