I've never played Journey. Apparently, it's extremely short (three hours or so front-to-back). I also hear it's wonderful.
Here's the problem: My PS3 is not (and will never be) connected to the internet. This means that all my PS3 games are strictly single-player. I don't want to buy it and discover that I've dropped a chunk of cash on a game where most of the enjoyment comes from playing over and over again with new people.
How much replayability is there in Journey if multiplayer is not an option?
