So Journey is seriously one of the best games I've ever played. Watching the first part of Nepsis, the foggy/glowy area reminded me of it, as you're dumped in a place with no explanation and you have to explore.

In Journey, you explore a desert filled with ruins in an attempt to reach a mountain in the distance. The whole point is just to experience the environment, and I really thing Pewdie would enjoy this. So I'd like to suggest that he play it on his alt account which he hasn't uploaded to in a while. You know, the one with the Skyrim and LBP2?
