Dex: vehicles and sleight of hand
Pre: adjusting to allow for Intimidation and Deception also
The Index: if characters have innate powers then they are on it. Its canon and I like it so I'm making it is a Complication. So hey when it comes in play auto HP for the character.
Not that characters even knows about the Index. Let alone if they are on it or not ... until it comes into play
The Accords: the characters hero-ing is just beginning. They will have to address signing the Accords or not during game play. There are pros and cons to each decision.
Sorry no sneak peeks behind the curtain. I would suggest having a mind set that allows you to "buy in" to the games premise and your character being part of a bigger story. If you can't see your character as part of a team (regardless which way they decide) then this isn't the game for you.
Lethality and other similar issues: If this were a video game I'd say keep it rated "Teen" or "R" for movies (of course that rating depends on an attentive parent) Me, I'm not a fan of casual lethality ... in the least.
Lol yes Heroic Feat
Tracking bracelets? I hadn't thought of that ... so maybe or not
Generic Asgardians Kree, Skrull (calling an audible on them) etc all valid Other aliens need to be MCU canon and give me a heads up first : I'm still only on season two of SHIELD AND Guardians Two introduced some stuff I might limit
