Just what everyone wanted - harder versions of Sonic 3's special stages

Valkyrie is amazing, Arenas is great, Olympus is slightly worse, and the Bow is the most broken gun ever released.

Again just a watered down version of Sonic 2. More additions and cool ideas, but the end product is held back by screen width and other limitations by the Game Gear.

EEEEEENTER THE GUNGEON 🎶

This is the Roguelite genre at its best. Quick, top-down, Zelda-style gameplay, but with dodge-rolling, guns (obviously), and hundreds of references and puns to boot.

Revenant is crazy, the Sentinel is fun, and Harvester is chaos.

Rampart is good, crafting is a nice addition, and the volt is a wannabe R99.

By far the best of the original trilogy, as it takes what was fun from the original (we don't talk about either version of 2), adds a better art style, faster movement, smoother mechanics, and the staple world map.

Sonic CD is everything a Sonic game should be. The biggest change from the previous two mainline titles is the fact that most of the time you can choose between two different paths; one is the extreme speed path, and the other is the slower, but more rewarding enemy-infested path. The only downside is how short the game is.

'Gotta go fast' sums up what Sonic the Hedgehog should be, but this first entry unfortunately just does not live up to the quote.
The buildup to full-speed sprinting feels sluggish, while some of the level design feels uncertain, as if Sonic Team couldn't figure out if they wanted to put more enemies and less speed sections.

Upgrades and fixes just about everything wrong with Sonic 1 + 2, in addition to adding its own new elements, such as different kinds of shields, less zones, and smooth transitions between said zones.

Definitely an upgrade to Sonic 1, however the same problems still exist, such as the startup of running, slippery landings, and slightly too many enemies and less speed sections.

The cake is a lie.

Watered down Sonic 1 that runs like crap on the Game Gear. Some neat ideas, but hardware limitations are stopped it from being a good game.

Building upon the Run & Gun genre, it borrows many aspects from previous games such as Contra, Metal Slug, and Gunstar Heroes, in addition to building upon them. Also its hand-drawn soooooo

Looks like an old NES rpg at first glance, but turns everything on its head similar to the Mother series. Also one of the only games that made me genuinely cry.
