Is it possible to create a in-game achievement system that saves the achievements your hero gets? (For a RPG). Such as, lets say, you reach the level max for example is 80, you get the "First Level 80", or if the level max is 1337, you get the "1337 Player" achievement. Or if you kill a certain amount of units, or complete a dungeon. How would all this be saved? Perhaps adding the achievement as a completed optional quest?
