An official revival would be great though. As long as they don't bring back that God awful Connor Mac Lyrr from King's Quest 8. I'd had quite enough of his plum-throated antics by about... oh, the first world or so. "What vile magic has invaded Daventry, and what is this?" Yeah, but something official based on the world of King's Quest 6, would be great.

Also:

Space Quest
Police Quest
Codename: Iceman
Laura Bow
Manhunter
Gold Rush
Jones in the Fast Lane

...

Zork! -- Wouldn't it be great if Actiblizzion Vivendi Universal brought this one back?! Again? :D

I'd like to see a new:
King's Field
Grandia

Panzer Dragoon Saga!

Go Saturn love.
