I recently beat Journey after picking it up from the PS Store for $7.35. All I have to say it was amazing. I've never played a game like this before but I want to play it again and again. The game is short and sweet and has high replayablility IMO. The graphics are also something to behold. The controls are great and simple. I'm going to try to get all the trophies.
It's only $10.50 this week and $7.35 for Playstation Plus members.
You should buy this game.
