Considering that over the course of me watching FM, I made the connection of Freeman's face to Ross's voice, seeing those old pictures clicked FAR too well in my head. Therefore, his current look did take me by surprise, but I was used to it by the end. Ross Scott is so much cooler than I could ever have imagined!
I'm perfectly cool with FM being put on the shelf. The amount of downtime deserved from the time put in to that series, Ross would probably suffer an existential crisis from taking such a long break.
I really look forward to more Game Dungeon. It's just as entertaining as FM, though I can imagine many disagree. I'm actually happy with whatever Ross puts out, apart from generic Let's Plays, because there's more than enough out there. I only watch Markiplier, and I struggle to keep up with that!
As far as suggesting ideas goes, I've been very inspired by the concept of Across The Universe, although of course suggesting anything FM-ish is off-limits:
I've found an FPS-mission that I think could make an alright ATU. It would probably have 2 or 3 episodes to it, so as to allow for dialogue. As far as production, I would make the whole thing myself, including script. The only input I'd request from Ross is his voice, for authenticity. More likely I'd give it a shot or get a mate to do it.
Generally, ATU could be a great community project, with people making their own episodes and getting Ross to provide the voice. However, he really deserves to put Gordon Freeman away for a good while.
