Dungeons and Dragons, but your character must be a self insert, and class is determined by your current abilities
Barbarian Must have a demonstrable temper, go off I guess Bard Must be able to play an instrument Cleric Must be involved in a religious organization Druid Must have demonstrable knowledge of, or passion for nature Fighter Must beat the DM in physical combat (hope your DM’s a wimp) Monk Must practice a martial art Paladin Must have a cause that one actively supports Ranger Must be able to fire a kind of ranged weapon accurately Rogue Must sneak up on the DM (Hard mode: steal their dice) Sorcerer Must have a powerful family heirloom Warlock Must work for a powerful entity (Corporations, The Government) Wizard Must have a College Degree or a 3.0 GPA
If you can’t be any of these you start as a commoner, and may become one of these classes when you finally satisfy these conditions.
