...and a poor attitude.
Very few things turn me off of a setting more than a timeline that's more than maybe a page a half.This is why I tend to shake my head at game settings that give long distant past events anything more than a quick mention. Does it matter who was Queen 500 years ago in most settings? No. Then it shouldn't be part of the setting material that you give to players, because it's nothing that's going to affect their characters' lives.
