A prestige archetype is a prestige class turned into a normal 20-level class, similar to an archetype or alternate class.
The goal when making these prestige archetypes has been to capture the flavor of the prestige class rather than to make an exact copy of how it would normally be. Attack bonuses, hit dice, class skills, spells, and class features have been unified and spread evenly over levels. This means that most prestige archetypes have their prestige abilities spread over the entire 20 level spread. Unlike how prestige classes normally work, these archetypes have a few complete class abilities rather than many abilities limited to a low level. In some cases, you get the choice of one of several class abilities rather than stymied versions of all the abilities.

Why Would I Want Prestige Archetypes?
You want to design a character around a specific prestige class but do not want to worry about jumping back and forth between class books.
As a GM, you want a streamlined way to make a prestige class-based opponent to challenge your players as quick as possible.
Many prestige archetypes are tightly focused on their theme, meaning that you spend more of your time adventuring and less of your time leveling up your character.
