Shadow of Mordor is looking like it will be one of the best games out this year and in a way feels like what Assassin's Creed would've been like had they elaborated on the concepts of the first rather than completely scrapping them off. The nemesis AI is one of the most next gen things we've seen so far i'd say, the story seems very promising and they seem to be taking good care of the lore. It takes concepts from other games but the way they're done, it looks unique.
Dragon Age Inquisition looks like a best of both worlds scenario between DAII and DA:O, i'm hyped.
Arkham Knight looks to be out of this world amazing. The new combat, traversal, visuals, just the scope of it all, can't come soon enough.
Witcher 3 goes without saying, and i'm optimistic about The Order: 1886, and there is also Isolation.
