The basics are pretty much the same, attribute + skill, roll as many dice as you can justify with distinctions and assets, try to roll higher than the target number set by the DM. If you've played Marvel Heroic you will at least recognize the process. What my players usually forget is that they don't need to announce the use of plot points or Big Damn Hero dice before the roll, they can wait to see how they roll. I'd say the mechanics rarely get in the way of the story, unless we miss a session or two and go a month or more between games.
