Blood was awesome !! Good old days. It was ported to the AMIGA (with 68060), so a DC port is definitly possible for a motivated dev.
90's and beginning of the 2000's was the golden age for the FPS. Of course there are still good FPS now but those good old FPS put the 1st stone.
No one lives forever was underrated, it was really good but almost forgotten compared to Quake, Doom, Duke Nukem... A remake could be nice (a legal one at the RE2 remake level).
