Recently reading the BTTF forums there was a thread that asked if people would be interested in buying a soundtrack, and while the results were mixed, I don't think such question was ever asked here...
Now I know this is out of TellTale's control because LucasRats owns the rights for the Monkey Island music in general so they would have to approve it first in order to TT to sell it.
Of course, it would be nice if we could get some acustic instruments and better synths, like in the Special Editions. But as those didn't get soundtrack releases, I find it more unlikely that Tales will have one.
But its just speculation, just curiosity.
Let's say TT could actually release a soundtrack with real instruments... Would you buy it then?
