All the games in the Spyro Reignited Trilogy are fairly laid back. Their open levels are more about exploration than serious challenge.
Finding all the gems and other collectables on your first attempt, however, can be quite a task. In fact, in Spyro 2: Ripto’s Rage! and Spyro: Year of the Dragon, it can be impossible to get all of a level’s goodies on your first visit. Needless to say, you’ll be wanting to return to many of them at a later date to clean up.
While you can laboriously travel back to previous areas and levels if you wish, there’s an extremely quick and easy way to do it: the Guidebook. Simply open up the game’s menu by pressing the start/options button and then open up the guidebook. From there, you can press left and right to switch between the worlds available in whichever game you’re playing, and up and down to select a level. Simply press A or X on the level that you want to go back to, and the game will confirm that you want to go there. One loading screen later, and the deed is done.
