I've been wanting to play this game since I first saw the preview but hesitated on paying full price for it because well.. it's a story game. I know PSN users got it free last year but I missed out. I FINALLY got during a sales and it was a wonderful game. The story telling the management of characters and making sure you don't make any bad decisions for them, the anxiety; all excellent. I really hated but enjoyed the whole fast reaction button pressing, I guess its necessary vs only choosing what to say next.
This game makes me want to finish all choices and get all trophies for it.
In summary: definitely a game you should try at least once in your life. But I still stand by my original belief of not believing it should be paid more than 29.99 for it.
