Community fans (that includes you, Dan Gibson,) stop clutching your Community DVDs and check this out—though be warned, the narrator can be a bit hard to bear at times.
Yes, that is indeed a video of the fan-made game "Journey to the Center of Hawkthorne," based off of the Community episode "Digital Estate Planning."
The game is downloadable here, but be warned, it is a fan-made game that's currently in its beta stages—you can keep up with each update by subscribing to the reddit community that's been working on it here.
I'm of the opinion that you get extra nerd points if you play the game while watching the episode it's based off of. On a related note, I think you could now easily guess what my plans for this evening will be.
