The thing that separates the TTRPG hobby from most others is commitment. The oft-stated platonic ideal of TTRPG gameplay, the long-running campaign, requires you and three to five other people to carve out time on at least a monthly (and preferably more frequent) basis for possibly years in order to play through a game of typical length. Although one-shots certainly exist, as well as con games where you need only bring yourself, fact is that if we talk about how mainstream RPGs are designed, the campaign is how they’re meant to be used. While every hobby improves with time and experience, your bicycle doesn’t care how often you ride it, your skis don’t care how many times you make it to a mountain each winter. Traditional RPGs, typified by D&D but including the vast majority of games published from a sales basis, have entire chapters of rules which are only applicable if you’re playing the game over an extended period of time.
