What the hell where are you guys seeing 450k for Journey. I can't find numbers for PSN games only Steam.

Sorry i read it wrong.  It said 450 titles not 450k.  But he did say it was right under 500k on my other thread.

I find it ultra impossible to track downloadable games, Dude!

as far as i am aware it is impossible, but that is why im going to ask about it because if they found a way that would be great.
