Okay, got through the story, and I think that is pretty good. Nothing amazing, this won't be most people's GOTY, but I think it's a solid experience. The combat is strong, the variety in characters is good, Kamala is great as the lead through most of it, and I liked all the Avengers in this, they are handled really well. The only Avenger who comes out on the...unused side, would be Thor. He kinda just shows up at a point, and you do use him in the story in parts, but everyone sorta feels more important to the story than him, though it's not like he's handled poorly, I'm just kinda realizing how things went.
The gameplay is overall good, there's a character type for everyone, I don't hate playing as anyone, though Widow is probably my least used, but I'll be giving her a better shot soon as I kinda learned her grappling ability a little better and that makes her more interesting to play than I thought. By the end of the game, you'll unlock stuff to kinda pick and choose how you want certain abilities to behave, it's not anything significant, like the character won't play noticeably different, but it's more like if you want this ability to give you health orbs or power orbs, or maybe it's about stronger rockets or more stun. It's minor tweaks, but it's a way to customize your playstyle.
This game does have problems and I'm not really talking about the live service stuff, that stuff is a mixed bag and doesn't bother me a ton, but to me, the most egregious stuff was performance. On a PS4 Pro, this game can chug, slow down like crazy in large maps with combat happening. It's bad, but it's never completely unplayble, it's kinda being like stuck in bullet time since you can still react, but it's pretty poor. I mean I put up with it for Xenoblade Chronicles 2, I can put up with it here, but I'll be looking forward to the PS5 upgrade. Good chance it runs better on PC. Hopefully they have some patches planned here soon as in the meantime, it needs some TLC to clean up the performance and bugs.
I can't strongly recommend the game because of that, like if you don't enjoy live service games, this won't change your mind, but there is a good enough game here that will grow and add more enemy factions, more story, more characters, more to do, but it's kinda rough, but Marvel fans should like it.
