Welp, might as well throw in my 2 cents
1. The Witcher 3: The Wild Hunt : I loved The Witcher 2, and I can't wait to just get lost in the open world CDPR is building in this one. The graphics are flooring me with every new piece of footage, and it looks like they're really focusing on the story and interactivity of the world and characters. Looks like a real 'next-gen' game.
2. Dragon Age Inquisition : I quite enjoyed the previous 2 games in the series. I like the world they built, I love the characters, and going back to multiple races, deep customization, a huge world to explore, and tacticality has me extremely interested. It helps that it looks gorgeous in Frostbite 3 too.
3. Halo 5 : Probably my top FPS franchise. Bungie built a detailed universe with Halo, and 343 is continuing to build on to it. I really liked Halo 4, and while I do play multiplayer, it's the story that keeps me coming back to the games. I really want to see where 343 takes this one. I want to know where the Chief goes, who he faces, the fate of Cortana, etc. I love the relationship dynamic between Chief and Cortana, and there's no doubt she'll come back, but in what capacity? Can't wait to find out.
4. The Order 1886 : A steampunk Victorian London built by Ready at Dawn? Yes, hell yes. I'm stoked for this one after seeing the downright gorgeous screenshots and reading the cover story from Game Informer. Lots of physics based destruction, interesting weaponry, characters that seem to possess mystique and depth, and Gears of War-esque combat, what's not to love?
5. Destiny : Always been a Bungie fan since Halo: CE, and loved every one of their games, so this will undoubtedly be great. A huge galaxy to explore, loot to collect, and customization galore. The fact that there's a traditional, dedicated single player story line shot this much farther up my list.
6. Watch Dogs : I was saddened by the delay, but an extra 5-6 months in the oven could be what the game needs. I was hyped for this ever since the E3 2012 reveal. I like Ubisoft games for the most part, and this new take on an open world Chicago has my interests.
7. Infamous: Second Son : Played and enjoyed the previous 2 games, so I'm definitely down for this one. New powers, bigger, more detailed and more beautiful world. Looks great.
8. The Division : This would easily be higher up my list if it had a true single player story campaign, but as it stands, the prospect of exploring an open New York City with other players, collecting loot and items to survive, and coming into contact with random strangers in city streets sounds awesome. It helps that it looks visually stunning as well.
9. The Witness : There's just something about this little island that's grabbed me. The mystery of it I guess. Beautiful music, a fresh artistic style, and what looks to be some unique puzzles. I can't wait to explore it all.
10. Thief : I'm not the biggest Thief fan, I enjoyed Deadly Shadows, so this is last on my list. I've been yearning for a nice stealth game and this looks like it'll scratch that itch quite well. Atmosphere looks great.
