I'm loving this game, a lot. The story's great, and the characters are likeable. Gameplay is pretty good, too (for what there is of it, lol).
My only issue is the R2 to walk. It gets me so frustrated at times, especially when I'm in a hurry and can't get around something because my character decides to do some wonky stuff.
I think my favourite character is Ethan, followed by Detective Shelby. Ethan's really likeable. Throughout the times I played as him, I just kept feeling bad for him. On the other hand, Shelby gave the story asort of humorous, less dramatic affect, but keeping to his role really well.
