”Its an unfortunate reality that over-saturation is a very real thing. We sometimes pour ourselves into our hobbies, and can quickly find ourselves up to our necks in questlines, missions, material grinding, and more. Its this onslaught of opportunity that leads to a player burning out in a game, despite going in with the goal of 100% completing their favourite game, or making a new character build.”
