I went into gotg expecting it to be like Mass Effect, and more RPG-like. Instead, it ended up being one of the most fun sci fi story driven experiences I've played in awhile.
Going to skip story, since it's probably best experienced firsthand, and if you don't know Guardians comics explaining it won't do much good anyway. Best way to talk about it is the writing was surprisingly good, and the comedy landed more often than not. The guardians interact with each other often to the point that it's clear this isn't their first mission together, and won't be their last. Every character you find and interact with feels like they were meant to be there. No NPC felt wasted.
First, it has Telltale style storytelling and choices, which do surprisingly matter. It doesn't affect the overall plot, but it has implications on how side characters treat you, and some even change larger events that come into play later on. So choosing wisely is a good idea.
Combatwise, it's a 3rd person shooter, but if that's all you see you're missing a lot. The game has what is called a "momentum" system that encourages you to switch up how you approach fights to get the most out of it, and get your team's skills faster. Between that, and the arena style fights, it kept me switching things up in terms of larger fights, and kept things interesting. For those abilities, everyone gets 3 main moves as well as an ultimate ability later on, on top of star-lord's element guns getting more elements as you progress. Between using ice to freeze enemies to take them out of combat, or using wind to pull snipers to you and punch out their lights, to using rocket's gravity grenades to bring enemies together to aoe them or have drax rush the group down, you have options. It kept the combat feeling fresh throughout.
Theres also some exploration and collectables. While most of the ones I found were pretty out in the open, I still missed a ton of costumes and other small things, that I'd like to go back and get later on. However, nothing game changing is hidden, so if you don't want to explore every nook and cranny of a level as you progress, you don't really have to. I wish there were some side quests and other optional missions though. They hinted at a lot of space marvel mainstays like Richard Rider Nova, Galactus, and a good amount of random weapons throughout marvel in The Collector's personal collection that may have made me nerd out a little bit.
The soundtrack was fantastic. I played all of it off stream, so I got to enjoy the 80s jams in full force, and it was absolutely worth it. Having the final countdown play at random during a big fight was hilarious, and appreciated.
The only real issue I had was some of the lines in combat were repeated a little too much to the people of Xenoblade syndrome. It got annoying pretty quick. Beyond that, I did have quite a few issues where Star-Lord would get stuck on terrain forcing me to restart, but the checkpoints are often enough that it didn't take me out of the experience.
Overall, I enjoyed the game a lot. I can't put partial stars, but would probably put it closer to 3.75 stars due to the bugs and lack of side quests. However, I am holding out some hope they fix the latter with story dlc, as the game deserves it. Not a bad game to start off 2022 with (even though the game came out in 2021).
