Not sure what you mean about too much happening? You stumble across a group of refugees in a druid camp and the druids want them out because they are attracting goblins and danger to the grove.
He means, we have Richard Scarry's Busy Busy Faerun where you have numerous NPCs all in animation loops eagerly awaiting player intercession. As noted above, in an MMO where immersion is linked to experience this is acceptable because people are more interested in the game play than the story, but RPGs it needs to be done more tastefully as much hinges upon how authentic characters and environments feel and will directly influence how the player responds to them. You never want quest opportunities to feel like those assholes on the Vegas strip handing out escort adverts.
