I saw that Firewatch was down to $16 on PSN, so grabbed it. Started it last night, finished it this morning; really enjoyed it. The art style is fantastic, and they've really captured the whole hot, dry summer vibe (the colour palate that it uses is simply gorgeous). Cool story too, and a lot quicker pace than the likes of 'Everybody's Gone to the Rapture'. Well worth the asking price.
I pretty much only bought it because I'm a fan of the Idle Thumbs podcast, and a few of the hosts work/own Campo Santo. Wasn't exactly my cup of tea but I thought it was well realised and had no complaints paying full price.
