How else do you explain to someone what dwarf fortress is, for example? You need dozens of hours just to get the grasp of mechanics and UI, less alone to figure out whether you even like the game. Same goes for many bigger games, for example mount and blade (bannerlord) starts off strong with a promise of you establishing and leading a kingdom but once you actually reach that part through tedious grind, you realize it was all for nothing and the game's a badly designed, shallow, unfinished sandbox with absolutely no vision or execution in that regard. Good luck getting to that conclusion without already investing at least 50 mediocre hours in it though.
