Why do scripters make everything overly complex?

[Hiro]

As the title says, why do scripters seem to make everything they script so complicated to the point of it never being released? Even when given as much time as needed to make something work, it never seems to see fruition.

Excuse my ignorance, especially if this sounds as if I'm insulting anyone, but what is the deal with there only being a handful of competent scripters left working on Graal who actually accomplish what they set out to script? Is it as I presume, a problem with being overly complicated with what someone is trying to achieve instead of keeping it simple? Or is there some other flaw in the collective minds of current or would-be scripters?
