I mean, you could still talk about the successes they had--the real stronghold is where the early 2000s to early 2010s was its strongest. So here's a headcount of Marvel games I've found on F95, we have Rogue Like Evolution based on X-Men Evolution, Cosplay Therapy based on 90s Spider Man show, but still there is a lack of Marvel games amongst superheroes like DC--fathoming some fun, hot sexy crossovers like Infinity Crisis and Infinity Crisis Island.
I believe DC, whilst still a mess, is starting to pick up the pieces albeit very slowly. The progress takes time because we knew they wanted to rush into the gigantic powerhouse of a tank that the MCU is, but strategy and planning didn't do good. Untimely efforts. Like my point earlier, DC and Marvel could pump out quality 2D stuff, but that amounts to whether they want to and how'd they invest in characters and lore.
