Not 100% sure on the rest of your list (other than Bully which was meh for what it was) but Shadow of Mordor is reall worth a play though. There are some things here and there you can tell will be better in the sequel but overall it took the open world, Assassin's Creed style genre and did pretty well.So far I picked up Geometry Wars, the Oddworld Pack, Bully: Scholarship Edition, Adventures of Shuggy, Rocketbirds, Blade Kitten, Hatoful Boyfriend, Raiden III, Momodora III, Nidhogg, Rock of Ages, Hero Siege, Pixel Heroes: Byte & Magic, Gods Will Be Watching, and Shadow of Mordor.
Luckily, the school year is almost over so I might actually get to play some of them.
Watchdogs is $16 now... scared it isn't even worth that from what I remember reading.
