Friend of mine stopped by and pointed out that while the 5th game in the season was only released in the US on PCs, it had a Japanese release on the Sega Genesis (Sorcerian).
I did a little more checking later and apparently while the two I mentioned are the only apparent US releases to consoles, much of the series actually was on some console or other
Side story to 2 - Faxanadu - NES (also released in US)
3 - Romancia - NES (Japan only)
4 - Legacy of the Wizard - NES (published by Broderbund in the US)
5 - Sorcerian - Genesis (Japan only) (also released in US for PCs by Sierra)
6 - Legand of Heroes - Genesis and SNES (Japan only)
6 side story - Legend of Heroes II - Genesis and SNES
and apparently, though this probably doesn't help us any as far as VC goes, 8 and a sidestory to 8 were released on Turbographx CD
So if there's some sort of big call for it, lots of these games could eventually be localized for sale on the VC.
