Flashback was awesome
I first played it on the Megadrive and loved it! My mum still remembers the game because she loved the animation of the man - it made that much of an impression. I later played the PC version with the additional and longer cut-scenes and then tracked down a copy of Flashback CD which never did quite make it out on the MegaCD but some of the changes weren't so good.
I used to have the sequel Fade to Black on PC but it disappeared and I never found it (found the box but not the CD). Never did finish that.
A HD re-make would be awesome, as would a complete re-build - I think if done properly and carefully it could work really well as a third person action/adventure a'la Tombraider.
Shame that Delphine disappeared like so many of the other great game devs of that time.
