I think you're doing both Marston and feminist theory a disservice here. The response to the outdated elements—and I readily admit that they are many—in Marston's Wonder Woman shouldn't be to negate his vision, but to critique and improve it. Just as later feminist theorists have done with the early feminist theory.
I also think you're missing that both the physical depictions of women and their role in plots in both comics and video games has been under constant scrutiny by feminists for a long time. I'm real curious on who those "people" are who you talk about in your last paragraph.
