Sonic Classics: Resurrection

Sonic Classics: Resurrection is a compilation remake of the five main classic Sonic games, released in August 2020 for Nintendo Switch, Xbox One and PlayStation 4. The games themselves are remade from the ground up in a new engine similar to the one used in Sonic Rush with completely new level design, and their stories are heavily expanded upon.
==Sonic The Hedgehog: Genesis==
A remake of the original Sonic the Hedgehog. Aside from the above alterations, the levels are a mix of the ones from the Game Gear and Genesis versions of the game, with Sky Base Zone only available with all six Chaos Emeralds collected. While getting fifty rings by the end of an act still provides access to Special Stages similar time the Genesis version, the Game Gear version's bonus stage is available with 25 rings after reaching a checkpoint. There are also only two acts per zone similar to Sonic 3 and Knuckles, with new mid-bosses added as well, and act 2 putting a slightly new twist on the levels. Short cutscenes are also added in to provide level transitions. This also applies to Sonic 2's remake, seen below.
==Sonic The Hedgehog 2: Rise Of The Death Egg==
A remake of Sonic The Hedgehog 2. Aside from improvements done to all other games, this one also adds in the scrapped levels from Sonic 2, along with levels from the Game Gear version. Similarly to the fangame Sonic: Before The Sequel, each level is accessed by either Sonic or Tails, with both of them having their own story campaigns reaching their climax in Metropolis Zone for Sonic, and Gimmick Mountain Zone for Tails. While Sonic is shown trying to stop Eggman's launch of the Death Egg, Tails is mostly following Sonic around while being pursued by Silver Sonic. As a result, the level order for both is heavily altered compared to any previous version of the game. Completing both stories with all seven Chaos Emeralds will unlock the Last Story, which adapts the Genesis version from Sky Chase Zone onward.
==Sonic The Hedgehog 3: Angel Island Adventure==
A remake of Sonic 3 and Knuckles. In terms of levels, this one is more intact compared to the others: all of the additions such as transitions and mid-bosses are already in the original for most of the levels. The levels themselves consist of every Zone from the original, along with full, fleshed out versions of the 2-player levels from Sonic 3. Once again, Sonic, Tails and Knuckles are shown going through separate story campaigns. While Sonic's story is mainly concerned with his evading Knuckles and Eggman to locate the Chaos Emeralds, Tails is separated from Sonic early on and spends most of his story solo, attempting to gather clues regarding Eggman's plan and warn Sonic, while Knuckles tries to stay one step ahead of both of them while evading a rouge Eggrobo's attempts on his life. All three stories reach a climax at Launch Base Zone as Sonic, Chrome Gadget for Tails and Flying Battery for Knuckles, and completing Sonic's story with all of the Chaos Emeralds as well the the others’ stories will once again unlock a Last Story, this time adapting Sonic and Knuckles from Hidden Palace onward.
==Sonic The Hedgehog CD: Little Planet Rescue==
An adaptation of Sonic CD. While not much of this has been finalized just yet, this installment's level design is perhaps the most heavily altered, as the game itself is slightly retooled into an all-out Metroidvania with a more detailed story.
