The remaster also made a few changes to content in the originals that was no longer considered appropriate. A few features included only in one or two of the original trilogy were unified across all three games in Reignited, such as the addition of 'skill points' in the first game, or Spyro's ability to roll from side-to-side in later installments. Each level is designed to match the size and layout of the levels in the originals. Spyro Reignited Trilogy attempts to mostly remain faithful to the gameplay of the original games. Additionally, the games feature a number of collectibles which must be acquired to make progress, such as gems, which also act as currency, and dragon eggs. Spyro's sidekick, a dragonfly named Sparx, acts as an indicator of his health, defending him from a limited number of enemy attacks. Each game is a 3D platformer featuring the titular protagonist, a juvenile purple dragon named Spyro, as he attempts to restore peace in a set of worlds specific to each game by vanquishing enemies. Spyro Reignited Trilogy is a remaster of the original Spyro trilogy developed by Insomniac Games for the PlayStation: Spyro the Dragon, Spyro 2: Ripto's Rage!, and Spyro: Year of the Dragon.
