I wanted to say that I am a bit leary of playing in an apocalyptic type superhero game setting. I've DMed one such setting and played in two others and they folded pretty quick.
The reason is that players are not really heroes. They are survivors. The players I've played with have eventually had issues with not being able to be heroes. The government is against them. The normal population is against them, etc. The PCs cannot really shine because very few NPCs appreciate what they do. Conflict does not equate to heroism.
So, I just wanted to say that I don't prefer to play in a game if the game is going to fold shortly after starting. PCs don't stop crimes, they don't save the world, they aren't heroes, they are just people with powers. If the DM and players are committed to playing in such an environment, I'm cool with it (although I do prefer playing superheroes that are indeed, heroes). I would caution people though that interest for many people wanes after a while of just figuring out the next sentinel to avoid. In such a world, PCs are often considered villains. Regardless of their motives, they are breaking the law and are criminals and terrorists. It is harder than normal to play a PC that most NPCs hate or fear.
I also wanted to know how Karma and Popularity work in such a world. Although I own the ruleset, I have never played Marvel, only Champions.
Does killing take a PC down to zero Karma in a game where almost everyone is often an enemy? Are PCs considered heroes, even though they cannot really be such? It seems a bit much to hold the PCs up to the same Karma standards as a four color campaign if the campaign is apocalyptic. For example, does property damage result in negative Karma? There seems to be several positive Karma actions in the core rules that would never happen in such a campaign, so it seems tougher to acquire Karma.
Not to say that I don't want to play. I love superhero campaigns and there are virtually none around. It's just that I have seen what happens in these types of campaigns and don't want to start if the campaign is going to crash and burn after a few months.
Also, when will the campaign start?
