My gaming group tends to prefer low power level campaigns. Rather than tales of epic heroes saving the world, we prefer tales of dirt-farming peasants sometimes succeeding at things. We tend to be much more invested in out characters when we feel they are defying the odds.
My question is: Using 5e as base, how can I incorporate starting a campaign with the party as a Commoner or other NPC class (effectively Lvl 0) and have them eventually progress into real classes after the first few seasons?
How can I adjust starting characteristics and gear to represent this?
I welcome all suggestions, comments, and advice.
