Fallout games have always had a 20-level cap. This is the 3rd fallout game in the series. You'd expect its game mechanics to follow the other two, even if it is in 3d and not 2d isometric.
I would expect it to follow the previous game mechanics. Unfortunately the other games do not all cap at twenty. I remember clearly going well past 20 in FO2 after discovering the in game strategy guide.
However, even for the "most hated" award, it's a tight race between ME and Vista. I'd say the hatred of ME is more intense, while the hate for Vista is more widespread.
I don't know, YOU seem like a nice enough guy. Though your self important need to have references to YOU in all caps is a little annoying.
