Is Metal Gear Survive worth it? Oh yeah, totally. Game of the Year. Honestly, I don't know why you haven't bought it yet! Death Stranding won't be able to compete with this. Sarcasm aside, don't buy this game, just don't. Yeah, the environments and visuals are kind of neato and the feeling of helplessness certainly comes across, but it's just a clusterfuck.
For an indie-RPG, this game runs well and has a good story attached. There are several characters to choose from and many attributes to learn and adjust as you go. If you were disappointed by Fallout:76, give this one a try as it feels a lot like one would expect a Fallout game to feel, without the disappointment!
Trails of Cold Steel II is a marvelous addition to the series. It carries the tone of the original perfectly, continuing a saga that sees its third installment hit later this year, while at the same time delivering an exciting story all of its own.
A solid if slightly disappointing offering, bringing fun and engaging urban conflict to the strategic landscape of the Inner Sphere. New mechs, enemy vehicles, missions and equipment round out the additions, for committed fans it's pretty much essential.
Crimson Keep is a decent enough title that you'll get some entertainment out of it, however, the story is barebones, the gameplay at its core is bland and basic, and progressing throughout feels like it's done at a crawl. On the positive side though, the design and overall look of the game are definitely noteworthy, being two aspects that help make this title more appealing from a visual perspective. Long story short, it's up to you in this case, I personally would save my money for something else.
