The thing I like about your Let's Plays is that your commentary feels like you're hanging out with the community without being annoying. It's not exactly a full-screen silent playthrough, but it's not exactly forced reactions that take over the gameplay either. Just enough commentary to be different from experiencing the game yourself, but offering almost like a buddy experience.

I wonder if there are ways to make this exact same system work with the community in a more involved and interactive way? With a smaller audience, maybe Skype in (with a TGN Skype account) some good members of the TGN/CS-Nation community if playing a multiplayer game (like CptainCrunch, signa, jimykx, etc.)? With a larger audience maybe offer polls in the website (or Twitch chat if you decide to stream live) on what to do for major choices in any game?

I'm not saying change the Let's Plays, but perhaps consider adding another kind of Let's Plays that involves the audience. Maybe even have one that involves playing a game with others in the community, while talking about the latest news and posting the discussion on YouTube as an archive. With your minimal commentating that doesn't interfere with the game watching experience, I'd like to think there are more options to consider to make it an even more transformative work and make people see how different this is from other Let's Plays.

Of course, this is merely a suggestion. I'm already happy with what you're offering right now, and I imagine this is meant for fun and not making a big deal out of it.
