My list is slightly odd in that I haven't played a few of these due to time restraints. However, because of them being some of my favorite franchises and reviews here and elsewhere that they hold up to franchise quality, I feel I can place them correctly.
1) Hearthstone. Easy pick for my number 1.
2) Shadows of Mordor (Only played ~30 minutes but a huge Arkham fan so I'm sure this will go here.)
3) South Park: Stick of Truth
4) Mario Kart 8 (Don't have a WiiU yet but I've owned almost every mario kart and loved all of them. Mario karts are the only racing games I play.)
5) Smash Bros WiiU (See above about Mario Kart. Only fighting games I play.)
HM: Child of Light. Tilted toward younger audience but well executed and delivers. Potentially a GOTY contender for some if you have a younger, gamer daughter/niece to co-op with (I don't).
HM: Divinity: Original Sin. Playing through it now and only ~5 hours in but I can echo that it's a great game with just a tiny bit of something missing to put it over the top. Then again, I'm not generally a fan of text heavy RPGs so it even getting an HM from me is probably high praise. For reference, I can't stand the Dragon Age or Mass Effect series'. I love RPGs, good stories, and reading, I just don't need 8-10 dialogue options for EVERY. FUCKING. PERSON. EVERYWHERE. They all say variations of the same asinine shit but there's always just enough side quests peppered in randomly that the completionist in me has to talk to all of them to make sure. I'd prefer it if the run-of-the-mill citizens weren't even interactable and that the dialogue heavy stuff was left for the actual story progression. The Elder Scrolls and Fallout series are more my style, I guess.
Honorable mention, dishonorable mention, and biggest disappointment: Destiny. Similar to others, started for me as a solid 9. Just fantastic. That dropped quickly over the course of leveling to 20 due to repetition of "holdout" wave clearing. Then at 20 there's this moment when the illusion shatters and you're just staring at this piece of shit triple A title and thinking, "Why the fuck did I think this game was so good, again?" Then you go online and read about the massive clusterfuck that was the game's production and realize what the game could, and should, have been. Then you read about the super-repetitive, cash-cow DLC that they call "expansions," as if you're getting a large content update, just so they can jack up the price. All you actually get is a few "new" 10 minute missions, almost identical to the old missions, to grind ad nauseum for a few months until the next "expansion." One of the biggest disappointments in gaming history I'd say. Most hype trains fall flat immediately when you start playing and realize the game blows but with Destiny the game IS really good for a short while. Out of the box for the first few hours it felt like the hype was well deserved and that just burns the players even harder later. That's why I think the game has so much venom thrown at it now.
Haven't played but need to: Telltale Game of Thrones, Telltale Walking Dead Season 2, Borderlands Pre-sequel, Vanishing of Ethan Carter, others I can't think of...
