I have excellent news for you if you played Marvel's Avengers, a game produced by Square Enix, and thought, "I wish this had simply focused on the single-player campaign instead of all this game-as-a-service ," because it does: Square Enix 's Guardians of the Galaxy, a Marvel game, has arrived to save the day. It's another evidence that single-player, linear campaigns are still relevant today because there aren't any microtransactions or multiplayer, and the story is very substantial. Guardians of the
Galaxy has plenty of good ol' fashioned fun despite its straightforward level design and simple but entertaining combat. These fundamentally sound elements combined with the massive amount of personality added on top will more than make up for Guardians of the Galaxy's lack of genre revolution.
You play as Peter Quill, a.k.a. Star-Lord, for the whole roughly 18-hour campaign despite being named after the squad. I found that to be a surprise decision, but it turns out to be one that works really well for the narrative being told. The primary plot is essentially what you'd expect from a cosmic comic book adventure—the Guardians are trying to pay off debt, learn how to cooperate, and perhaps save the galaxy—but it's framed by much more intimate experiences for Peter. The end result is a compelling narrative that successfully strikes a balance between its nonstop barrage of spectacle and humour and a few sincere emotional moments,
for both Peter and the rest of the crew, including Gamora, Drax, Rocket, and Groot.
Although the plot of that game is also fully linear, the Deus Ex roots of its creator, Eidos Montreal, are unmistakable in the amount of dialogue options available to you. There's rarely a moment where the Guardians aren't talking, which is welcome when the writing and performances are all as funny as they are. You're constantly given options for how Peter will react to different conversations, whether those are during important story moments or while walking around chatting with your teammates. 
The majority of these speech options are purely for fun role playing in an otherwise well-paced plot, but some of them may have unintended consequences.
For instance, using the appropriate dialogue options to save a character at one time can cause them to later return to assist you. Another time, I made a decision that led to a straightforward stealth portion in the following level, only to learn after finishing the tale that the alternate choice would have changed the level's entirety into a major shootout. The core of this campaign will probably look very much the same for everyone, but these minor variations did give my playing a unique touch and made me more eager to try New Game Plus to see what else might have happened. Each playthrough is enhanced by your decisions, which is a nice small touch.
Yet, throughout the entire game, battle was always engaging. Some of it can be attributed to the adversary design, which is sufficiently diversified to force you to use various elemental attacks to exploit weaknesses or destroy shields, as well as larger enemies who can be stunned by specific skills. Each of your comrades has a different role; Groot can bind targets, Rocket has the highest AOE, Drax focuses more on stagger, while Gamora typically deals significant damage. It's fortunate that their
abilities have an impact because without them, you'll be dealing with almost all of the damage; your teammates' auto-attacks have a damage output comparable to that of an aggressive massage.
Not only is the story played, but also other scenes.The banter also keeps fighting interesting throughout. Honestly, there is a tonne of voiced speech in this game, and the interaction between each team member is both enjoyable and educational because you can watch how their relationships change as the plot progresses. There were probably occasions when I heard the same phrase repeated far too frequently, but overall, the range of these barks is astounding.
That meant fights that were excessively similar could yet acquire fresh appeal based on their setting or the dialogues that occur during them.
Even during fight, dialogue options are available through a super move called The Huddle. 
Battling a big alien squid boss while Wang Chung's "Everyone Have Fun Tonight" is playing has got to be one of the most ridiculously happy experiences I've ever had.
