Yeah and you know what tabletop RPGs aren't? Good games. Let me explain.
A game is a test of skill for the purpose of entertainment. Tabletop role-playing "games" (for the most part) do not have rigidly defined rules and expectations–rather, it's the dungeon master that makes and alters the game at any given time. In this environment it is impossible for the player to hone their skills to overcome some challenge because the skills being tested at any moment are always subject to flux by the whims of the dungeon master. Tabletop RPGs are more akin to very elaborate renditions of playing Power Rangers or Dragon Ball Z on the playground, where you use your imagination to make up new things as you play, rather than games. They're very good at having a fun-filled night of surprise with your friends, but their mechanics, which were never intended for the construction of an actual game, become a disaster zone when transplanted to singleplayer game contexts.
