I'm finding the campaign to be pretty enjoyable in spite of the bugs. I think the writing and voice acting in the game are really strong and all 6 Avengers are pitch perfect. I actually prefer the game's versions of Thor and Banner to their MCU counterparts, and Nolan North's Iron Man is a delight (which shocked me because I didn't care for his delivery of lines in some of the trailers, but he won me over big time in the campaign). Kamala is perfect, of course. The Disney Plus version has a lot to live up to.
I also commend the game for taking MODOK completely seriously and never turning to wink at the camera. This is the most I have ever seen his human alter ego focused on and they give George Tarelton a pretty well defined, evil personality. His voice actor kills it.
While the gameplay isn't super deep and the missions and enemies are repetitive, it is still real fun to play. All 6 heroes feel very different from each other and they bring a very unique flavor to the proceedings. I think Thor is my favorite by far. So, lots to like.
However, one weird thing with the story, why does it feel so much like an X Men game? The Inhuman slit is pretty good, but it's such a bizarre choice to essentially transplant the core themes and ideas (all the stuff with AIM robots hunting down superhumans felt so DoFP to me) of the X Men into an Avengers game? The Avengers are usually more about politics and the complexities of celebrity culture than they are about racism. Again, it's not necessarily a bad thing, but it makes me scratch my head.
Overall, I'm having fun with the game. I'm on board for future story driven DLC and any sequels.
