I think the premise is basically “you are against the corporations” so you need enough buy in there for the players to motivate themselves.

I’d maybe have each player name a corporation that has wronged them, and how, at the beginning. Maybe present the corporations by name/mandate first, get everything all tied together?

Problem is, a setting seems to suggest 4-5 agents / 4-5 projects / 5 events / 5 issues / 5 secrets. It seems a lot like TechNoir in that way where you need a big table of stuff to start connecting dots.
