Also, Alone in the Dark didnt age well. I did play it a few months ago but it looked cr*p and gameplay was very, very slow. Dont bother with that.
Those old Poly based games don't age as well as the sprite based ones do they? But still, this game has the best story line out of ANY in the series, and is really quite creepy. In fact I'd almost go as far as saying that the only Horror adventures that are worth two shits are the ones based upon the writings of H.P. Lovecraft, some of which can be emulated well on the Amiga.
Prisoner of Ice would be one title I'd suggest if you can run DOS Box fast enough.
Aghh wait, and there are more that actually made it to the Amiga!!!
Dylan Dog: Through the Looking Glass
Anchorhead
The Hound of Shadow
The Lurking Horror
and of course Dark Seed II which again you'll need Shape Shifter to play, but hey, at least we got part one on the AMiga.
