I read about this game months ago, when it was released I was very glad to see that it was on PS Plus from Day 1. Since I am already subscribed to PS Plus, I have downloaded it and playing it right now. I really like the game up until now.
I will probably try the studio's other games like The Messenger when I'm done!
Opinion: I think all of the characters have very interesting, often emotionally moving arcs, but I can certainly understand why most players are focused on one character in particular.
That said, it's a game that demands 100% to get a really satisfying conclusion though. That wouldn't be a problem, but 100%includes collecting all 60 of the arbitrarily hidden shiny things across the game, which is quite obnoxious.
