I've played through Journey several times, gotten all of the hidden stuff (that are known), and have an awesome white jacket because of it.
I've made five new friends via PSN due to Journey. I always stick around till after the credits to see who I've played with and either I'll send them a message, or they'll send me one and we friend each other...
How fucking magical is that? Since we experienced some kind of strong bond, it's impossible not to be friendly to others after a game is over and instead of people I don't know of clogging up my friends list, I have people that I actual like for no apparent reason.
Just wanted to get that off my chest.
