After a couple searches of the forums, with nothing turning up. Here are a couple IPs Id love to see FFG get ahold of and produce a remake of:

Conquest of the Empire
Shogun
Fortress America

and of course the most unlikely of them all (due to the nebulous copyright/settlement)
Darktower (Id actually like to see a version of this without the electronic component as well)

Interesting. I'm sure there are lots of games out there that, with an update, cooler components, and that FFG touch, could be really cool. Lots probably aren't that bad, and there may be some real gems.

I was always hoping for a Dark Tower remake. I imagine a tower with a video screen, animated battles, etc. With an SD card slot or something for new quests and abilities. Sigh. It will never happen.

Another vote for Fortress: America. It's not impossible because Avalon Hill/Wizards/Hasbro had the Cosmic Encounter game before FFG took it, so...maybe?

Lastly, I would hope for City of Chaos. If they give it the same treatment that Z-Man games gave Tales of the Arabian Nights it would be wonderful and a nice competitor to that game.
