We wouldn't want that either.  You would have to have full creative control and final say.  I'm on the outside looking in, but I don't see why anyone would bother giving you notes on a Monkey Island game.  What you've done with MI speaks for itself.  

I understand your principal, but you birthed MI into the corporate world.  Who knows if it ever exists outside of it?  In this case, I think the story is too good not to tell regardless of who gets to say they control the property. Just make sure you're well positioned when they write up the paperwork, because your fans are going to make that game a hit.
