Despite the performance issues, Subnautica is definitely a title that you shouldn't sleep on. The open world exploration and survival mechanics are on point, and the world is massive, deep, and rich in detail; it's just a shame that it's being held back a little bit by problems with how it runs.
Between its incredible story, excellent gameplay, and surprisingly fantastic presentation factor, Thronebreaker: The Witcher Tales is yet another masterpiece from CD Projekt Red that pushes the boundaries of game design and proves that anything, even a card game, can be groundbreaking if done well.
Space Hulk: Tactics is a solid entry to the strategy game category for Xbox One users. The lack of a strong campaign and good progression system are unfortunate, but this doesn't hold the title back from being highly enjoyable. The unique and polished gameplay experience makes it more than worth your time.
Despite the unimpressive graphics, Fishing Sim World is definitely a game you should get if you like simulators and want to see what a simulated fishing experience is like. Personally it's not really my thing, but I can definitely see people who do like these types of games getting... hooked on it.
If you're looking for a (mostly) peaceful gameplay experience that relaxes you and immerses you into an artificial world, Planet Alpha is definitely for you. The game's length is short, and people that want an action experience will get none of it with Planet Alpha. But aside from that, it's a game that you shouldn't pass up.
Despite the variety of issues I have with the experience, my friend and I enjoyed our time with it and will likely play it again. However, if you're interested in something more challenging and intense, or simply want something with better presentation, Strange Brigade isn't the title for you. Instead, I would recommend checking out the Left 4 Dead-inspired Earthfall.
If you don't mind doing extensive web research in order to understand the ins and outs of Graveyard Keeper's gameplay progression, you'll be able to enjoy the best of what the game has to offer. However, if you would rather not deal with the hassle, I recommend passing on this one and checking out Stardew Valley instead.
