The beauty of superheroes is that they appear in an incredibly wide variety of genres and settings. I realize that MWM likely already has all of their lore for launch pretty much locked, but I want to get us started on talking about possible future expansions of the game, and if it's not locked yet, great! here's some more ideas to possibly explore.
What I want to ask is what genres do we as players want to see in the game, and more importantly, what are ways that these genres feel unique to one another in gameplay and theme. It's one thing to put a skin on o group of baddies and say, "here you go. A bunch of aliens," and making them pretty much standard mmo mobs that pretty much work the same as the fantasy elves or street gangs. It's another to create a unique player experience depending on the theme of the quest line you are on. I recently made a thread on horror, suggesting ways to make it feel unique.
What genres do you guys want to see? What makes them unique? How can we make them feel the way they should through gameplay?
