Pillars of Eternity

Down here is a list of every place you need to visit for the achievement, 152 total (https://steamcommunity.com/app/291650/discussions/0/61845803...). Some area's are only accessible through quests, like one of the dwellings in Hearthsong. The achievement has to be done in one sitting but my game crashed and still gave me the achievement, as well as others that need to be done in one run like super murder. So maybe crashing the game and restarting doesn't reset but don't count on it.

The Xbox Series X/S may makes it a bit easier. The quick resume function that the console offers seems to prevent the achievement tracking to reset. Tested if with a few achievements but not the long ones like this one. But it should work al the same. Keep in mind that an power outage will result in a reset so maybe don't take to long if you're going for it.
