If you were in charge of a hypothetical sequel to Shattered Dimensions, which Spider-People would you include? And which level/villains?
Personally, I think I would include five Spiders:
Amazing!Peter is a shoe-in, and I think he can largely keep his web-focused gameplay. Personally, I think his levels/villains should focus on lesser-known villains or ones who haven't been in games before, so I think these combinations would be good: Overdrive/Manhattan Chase, Black Tarantula/Shadowland and Kindred/Graveyard.
Miguel O'Hara can also be carried over largely thee same gameplaywise. I remember his levels being very same-y aesthetically, so I think focusing on variety would be good. I also think that 2099 was the universe least well-represented by its villains, so focusing on rogues from David's original run would be ideal: Venom 2099/Sewers, Discord/Virtual Reality and Thanatos/Alcehmax Tower.
Miles is a no-brainer, but in keeping with the whole "alternate universe" angle I think he should focus on rogues from his time in the Ultimate universe, especially with those associated with Roxxon since it could provide a useful through line for his levels: Human Fly Twins/HYDRA base, Taskmaster/Triskelion and Roxxon Brain Trust/Roxxon Tower.
Gwen is also a no-brainer, and I imagine she would focus on her symbiote powers like Ultimate Peter in the original. She's also the one I'm least familiar with, so someone feel free to offer different suggestions: Harry!Green Goblin/Midtown High, Black Cat/Concert Hall, Matt Murdoch/Kingpin Headquarters.
Mayday I think could also be interesting. IIRC while she largely has the same powers as Peter, she does have a more robust Spider-Sense as well as a more expansive version of wall-crawling. Could probably make some more platforming-focused levels with her: Mayhem/Oscorp, Red Queen/Avengers Tower and Daemos/Forest Hills.
