So what exactly makes Earthbound/Mother or Digital Devil
/Persona more real world than a setting with super heroes? They all have fictional attachments to the settings, but they still name real world locations, reference real people and the like.
What, if you weren't so strict as to not allow alternate histories, then Fallout would count too. But you don't hold other genre to such standard. You should know that the soldiers of the 19th and 20th century did not have checkpoints to respawn at or holographic images to stand on to get new weapons, nor could they mend wounds by picking up health packs or using rations, as the Call Of Duty games would have you believe. Its an alternate history in everything but name.
