Little late with a thread for this, but... here it is!
Some crackers on this one. I'd heartily recommend paying above the average to nab Hotline Miami, brilliant game. If you don't fancy paying too much though, Thomas is Alone will tide you over will.
Similarly, the Telltale Humble Bundle is running for this week only, so if you're a fan of point and click adventures, jump on that now. It's pretty much their entire recent library, and beating the average gets you the full Walking Dead game, all the episodes, which would cost a pretty penny to buy on Steam.
Good deals all around!
