If you're patient on M:AA, you can do everything without pay-to-play, particularly after they added repeatable Level 300 as a way to earn Gold, but it takes a lot of free time and quite a bit of strategy.

The whole slotting stones into hero's armor to strengthen stats has always made me view the game as Final Fantasy: MARVEL Edition, but I think it's really interesting that the fact that the sudden appearance of Iso-8 there unknowingly foretold the impending renewal of the universe and is a pretty slick way to explain what it is and why the incursions brought it to Earth-12131.
