This last line made me laugh at loud. the concept of Ironman Gaming has been around for DECADES. Devoted players would want to up the challenge of a game and would create rules for playthroughs challenging others to stepup and try. Add to this that stepping outside a games mechanics is often what leads to the best RPG play. When you use and exploit every game mechanic there is a term from back in the day, we called it min/maxing.
Maybe your position is true among younger gamers. Not sure why as this is just a test of will power over the game. For old school gamers however the Ironman style challenges is a time honored and revered tradition.
Is that so? Name 5 other very big, trivialy easy, slow paced, heavily RNG based, story driven games that have a popular scene doing iron man challenges.
