Spoilers for Journey follow.
I didn't really know what I was getting myself into.
I'd heard about Journey's innovative multiplayer feature, of course; it was impossible to follow video game news in 2012 without reading about how your Journey journey can be peppered with silent, anonymous companions who are pursuing the same quest as you. You can't talk to them, but you can see them, jump with them, and share an adventure together.
I also read—and ignored—Kirk's tip for starting Journey. Thank god.
