Does anybody other then me remember a game called Magic Realm?
I would be in heaven if FFG remade this game.

An old avalon hill game i loved to play
Between the many games from the past that never had a reprint / reissue, I'd love to see again 1830 (and its fellow games, set in the UK and in Germany). Too many good things from the past have disappeared.
I wouldn't hold my breath waiting for FFG to remake Magic Realm. That's simply not their kind old game. They need an angle where they can put a bunch of plastic in the box. 
Seriously, I'd say that Valley Games is your best bet of a remake there. They're already demonstrated a desire to remake old classics and they do a good job. Just look at the reprints they've done so far : http://www.boardgamegeek.com/wiki/page/Valley_Games_Classic_Line. Z-Man Games has expressed interest as well although Tales from the Arabian Nights is the only old reprint of theirs that comes to mind.
