I have had so many great experiences this year thanks to my vita.
Games like olliolli, Minecraft, Toukiden, SSD, Murasaki baby, Pix the Cat, TWD S2, Metrico, Unfinished Swan, SAO:HF, BOI:rebirth, RL, Don't Starve, Swapper, OP: Unlimited World Red, Rezogun, Akiba's Trip, Child of Light, Natural Doctrine, Velocity 2X, GOW collection, Dustforce, Starlight Inception, Fez, Destiny of Spirits and my game of the year (and IMO the Vitas GOAT even though I haven't finished it yet).
It has been a fantastic year for the Vita game library, but I can not wait for 2015 when I will be able to play games like Helldivers, Galak-Z, Banner Saga, Bastion, geometry wars 3, Shovel Knight, Risk of Rain, Hotline Miami 2, Oreshika, Octodad, Super Time Force, Grim Fandango, Broken Age, Big Fest, Severed, Tower fall, Nova 111, Citizens of Earth, World End Eclipse, Zodiac, Hand of Fate, DFS, SAO:Lost Song, Olliolli 2, Digimon Syber sleugh,
Tokyo twilight ghost hunters, Jump Ultimate Stars vs, OP PW 3 and PS Now (EU).
these are not all the games that are announced, but my personal list of games that I'm looking forward to and this is just the games that we know about (and it's still 2014).
Edit: Is RoF, Ni No Kuni, Mass Effect, Dragon Age, Nier, VC or Dishonored on PS Now?
