This is a great idea, but from my understanding it is wrapped in legal issues. Sierra was sold and thus the intellectual property rights for the games as well. It is my understanding that the owners of the rights aren’t terribly interested in seeing these sorts of games return.
So in lue of that, the next best thing would be to make new games in the spirit of the Sierra style games. We have been looking into the interest level of these type of games and may build a game engine to fascilitate this genre should interest prove high enough.
So since you the old Sierra games won’t be coming to systems near you, who is up for new adventure games in similar fashion?
Sincerely
