1.The Witcher 3: Wild Hunt - My most anticipated game of 2015, the game has gorgeous graphics, gigantic world and a fantastic art direction. The new open world structure will do wonders for the series quest and mechanics (and falls in line with the books and lore structure), while adding new ones like detective mode and monster hunting, not to mention epic horse and boat riding. I was already satisfied with TW2 combat, so it can only improve. My only worries is how PS4 will handle the game game, performance wise. Given the dev's previous track record, i'm sure The Witcher 3 will be a 10 for a lot of people, and a commercial success.
2. Assassin's Creed: Unity - Last AC i enjoyed was 2, while 3 was a massive disappointement, and skipped all the other ones (Brotherhood, Revelaitons, Liberation and Black Flag). But Ubisoft really surprised me this year. The French Revolution setting is probably the one with the most potential since Italy, and Paris is a masterpiece of architecture, and will be a joy to travel around it. This especially thanks to the wonderful game engine that surprised everyone (dem interiors) that pushes new animations and new parkour mechanics. Also, co-op seems really cool, can't wait to try it with with friends. Still, there are a lot of things to prove: a protagonist that dethrones Ezio in interest; a new and improved stealth system; a story that isn't written by a 12 years old kid; useful and interesting side content. Come on Ubi, you can do it!
3. Dragon Age: Inquisition - Having never played a Bioware game before, i can see it with an outsider eye: the game has a wonderful world, an awesome soundtrack, and a combat system that seems both fun and challenging, mixing fast (for common enemies) and tactical (for bosses). I'm honestly not expecting much from characters and story, i just hope main and side quests will be interesting enough.
4. Destiny - Still one of my most awaited games, but recent videos toned down my hype a bit. But the "Experience" trailer pulled me back in. I suck at FPSs, but artstyle, universe, rpg mechanics and multiplayer pushed me over the edge. Hope to get into Beta to confirm my expectations.
5. BloodBorne I played DeS and DS, but never got to the end because they're way too frustrating. Also, graphics sucked. But with BloodBorne, being on next-gen, with supposed amazing graphics and an outsanding Victorian-era art direction that gives a strong Castlevania vibe, i'm really open to give another chance to FROM. I hope they develop some new mechanics, and especially let me play with my friends with a real co-op.
6. No Man's Space - Both reveal trailer and E3 ones blow me away, can't wait to play it on PS4. Still, apparently it's not a MMO and iirc you can't play with others, which suck big time. I also want to see how every mechanic is structured (weapons, exploration and such). I'll keep an eye on it.
