I think it depends what you consider an escape from reality. I mean games like Persona, Stardew Valley, Animal Crossing and Elder Scrolls are definitely perfect mediums for escapism.Rpgs in particular are derived from tabletop rpgs which are heavily about escapist fantasy in the form of shared storytelling.I think part of this desire to do anything in an MMORPG, is rooted in the old RPG trope of, a handful of adventurers coming together to form a party. In tabletop rpgs, metagaming tends to be heavily frowned upon in favour of promoting players to make flawed characters with distinct weaknesses so their cobbled together party can try to pull together to brave the world the DM throws at them. Single player rpgs tend to do a passable job of capturing that freedom letting players do what they what they want in them, soloable or low difficulty tend to content in MMOs do so too, it’s only when you get to things like Raids and PvP in MMOs where the freedom that rpgs are supposed to provide seems to die and everyone is expected to conform to a meta, and that imo is why where ever a meta forms you get so much conflict from players who want to play their own way.
