Apparently, based on the Broken Sword remake's sales, we may be getting more adventure-related fun from Revolution. They're actively considering it, though the interest, sadly, seems to be focused on more remakes.
Still, the possibility of a new adventure is out there. I recently played Beneath a Steel Sky(didn't snag it until I wanted to test out the GoG download and install process), and I'd be pretty excited to see another entry in that series.
Anyway, good news all around, right?
