Especially those that have either never gotten a video game adaptation or are underrepresented in video games. For me, I would love to see Gambit game. The X-Men series as a whole (independent from the larger Marvel comic book universe) has a lot material for a video game. Yes, there has X-Men games in the past but I want to see solo Gambit game; in style of Arkham Knight. But that’s just my idea. What are some of yours?
I want the Marvel Ultimate Alliance model to come back. Build a four-member team from a huge cast of Marvel characters. Have their powers synergize with each other in interesting ways. Get team bonuses if you have the entire Fantastic Four, or Defenders, or what-have-you. Equip different costumes from different continuities for different effects. Action RPG elements.
There were a couple for the PS2 era that were awesome, and then they made one for the 360 that had better graphics but actually a much smaller cast and wasn’t as good as it should have been given the enhanced technology. And then nothing since. Midnight Sons sounded similar but I haven’t heard great things about it. The template was perfect! Just keep making more of that!
