As the title says, this list is for Progression Fantasy series. This list will exclude most LitRPGs because my brain prefers them to have their own list.
As the title says, this is my tier list for strictly LitRPGs. Series ranked S and A are ones that I would confidently recommend to others, even if the person isn’t even familiar with LitRPG. Series ranked B; I’d strongly recommend to anyone that are fans in the genre and enjoy discussing about. Series ranked C are stories that have at least one good quality that can be appreciated, but overall aren’t for me. Series ranked D…well, “If you don’t have anything nice to say…”
