Being a fan of DL and SA myself, I've owned just about every version ever available. Believe it or not, the Amiga version holds up extremely well. Space Ace, Dragons Lair and Dragons Lair II are all classics. Yes, they are spread across many floppies, but even so, it's very quick and you'll hardly believe you're messing around with floppies at all (if you've got at least 2 drives that is - lol). There are WHDLoad versions out there too if you can't track down the originals.
The PeeCee and Mac versions are good too. I remember seeing the DVD's, but never bothered since all the others are excellent for what they are.
