I'm playing through Gotham Knights solo. For the under $10 I spent on it I'm enjoying it, although it has the occasional annoying section. It does a decent job of making the four playable characters (Batgirl, Nightwing, Red Hood and Robin) feel different from each other, and gameplay wise its similar enough to the arkham games that I didn't have any problems getting into it.
I also just bought Suicide Squad: KJL because it was $5 for the deluxe edition. i'll get to it eventually, I don't have high expectations but at that price it was worth it.
For non-story based games Marvel Rivals has really caught my attention. I've played hundredes of hours of Overwatch 1/2, and this is hitting that itch but with some fresh twists and cool characters.
