Zer0 Sum tells the best story and introduces the best characters in the Borderlands series. As a Telltale game, the humor tends to fall a bit flat at times, and it lacks the drama Telltale do so well.
Shovel Knight was fun for a while, but it didn't do enough to keep my interest the whole way through. A very good old school platformer that doesn't do enough to earn a place in modern gaming. If you're feeling particularly nostalgic, go ahead, otherwise you might want to play something a bit more ambitious.
Echoing classic horror stories from authors like H.P. Lovecraft, The Vanishing of Ethan Carter is a wonderfully unique experience. It's not without its faults, but if you can get past the shallow story and gameplay, you'll be in for an immersive treat.
Inquisition is everything I want from an RPG and more. Unfortunately the more is countless hours tedious collectibles and fetch quests. Still, it's the most ambitious Bioware game yet, offering an action packed main quest of around thirty hours, a beautiful world to explore and interesting characters to meet. This comes highly recommended and should be an instant purchase for anyone with the time to spare.
