I agree with just about everything named in this thread. Also the Monkey Island games, which may have been fairly popular back in the day but are essentially forgotten now.
I'm also not sure how mainstream the Heroes of Might and Magic games are, but since turn based strategy tends to be a pretty niche genre (hell, PC gaming is pretty niche) they probably qualify.
I'll also add the "Soul Blazer trilogy" on the SNES (Soul Blazer, Illusion of Gaia, Terranigma), which are very good action RPGs that retro gamers now tend to love, but didn't get much attention when released.
