I'm not sure how to feel about the lack of player identification in Journey.
I have a fun time exploring with someone, but then they log off and I'll never be able to see them again. Even if I do happen to run into them, I'll never know for sure if it's really them because there's only one single audio ping to communicate with.
Yes, I realise that that could be interpreted as a fantastic artistic statement about... I dunno... societal isolation or something, but in that case it's a fantastic artistic statement that makes me feel kinda bummed.
Although you could say it's a good kind of bummed feeling... AAARRRG!
Maybe I should just teach myself morse code.
