Why hasnt anyone mentioned "ScummVM" yet? You can throw it on any PC knocking around (or iphone, psp, gaming device!)... and I think it even has Amiga versions for them games too! - BASS is up for FREE DOWNLOAD on the ScummVM website! ;-)
I would however recommend getting "It Came From the Desert" for the Amiga... now THAT WAS STORYTELLING!
edit: someone DID mention Scummvm, sorry... I went into more depth though! ;-)
