10. You pay attention to little details no one else cares about.
OMG you guys! Captain America's costume from Captain America: The Winter Soldier implements the trademark "A" on his cap, the Ultimate Captain America helmet without the wings, and the wing and star chest emblem from his run as Steve Rogers in "The Heroic Age!" This is no different from being able to tell someone is wearing a LBM 1911 sportcoat because of the telltale lapel pin inside the buttonhole. These details may be important to you, but in the grand scheme of things, not a lot of people care.
