If you are a shooter fan, you owe it to yourself to play DOOM, just for the campaign alone. The game is a master class in how you design a level; not in how it looks like, but how it functions.
You're going to be hearing a lot about Overwatch for a long time to come, not just because the game is stellar, but because of Blizzard's incredibly long track record of supporting their games post launch. You don't need to wait for a sale, the game's full price carries a ton of value both looking at today and with what lies ahead for the game. If you aren't already playing Overwatch, you are missing out.
Final Fantasy X-2 is a fundamentally sound JRPG from a game mechanics perspective, but its cheese factor and lackluster narrative pay off hold it back from being anything more than "the other one." There are interesting ideas at work, and Square's logic of trying to present a different look at the same world makes sense, it just doesn't always work in its favor.
Asemblance takes inspiration from the likes of PT, The X-Files and The Twilight Zone and brings them together in a package that hints at a franchise with a future that's bigger than what it currently offers.
Soul Axiom initially holds promise, but design flaws, a convoluted narrative, and constant guesswork make the puzzles feel arbitrary rather than rewarding.
If you're already a fan of The Witcher, there's no reason why Blood and Wine shouldn't have a place in your collection.
RotTK XIII is a bit of a mountain to climb for new players, but if you stick with it, you will unearth the deepest strategy game on the PS4.
I recommend Abzu to people who have enjoyed the kind of work thatgamecompany has put out because it looks like Giant Squid is here to do the same thing. Some might argue that $20 for 2 hours seems like a hefty price tag, but it's all about how much you can appreciate the little things that go into game design. Abzu is a very good game, but it lacks that same amount of punch that Journey so effortlessly delivered back in 2012.
Headlander is worth the price of admission, just be warned that its combat can lead to a fair share of frustration.
A budget-priced experimental title whose success lies in its narrative over its game design.
