Honest skips / for later
Sonic the HedgehogStart here
A short, readable way to see the first Sonic formula, though the sequel is smoother.
Sonic CDFor fans
Important and stylish, but its time-travel structure is stranger than the clean Genesis entries.
Sonic 3 & KnucklesStart here
A bigger, more intricate classic entry to play after Sonic 2 or Mania.
Knuckles' ChaotixFor fans
A curious 32X experiment with a tether mechanic, best treated as history rather than a first stop.
Sonic 3D BlastFor fans
Historically interesting, but its isometric movement is not what most people come to Sonic for.
Sonic AdventureStart here
The first major 3D Sonic is uneven now, but it explains the Dreamcast-era style better than anything else.
Sonic AdvanceStart here
A solid portable 2D Sonic if you want something after the Genesis games.
Sonic HeroesLater
The team-switching idea is memorable, but it is clumsier than Adventure 2 or Colors for a first 3D pick.
Sonic RushStart here
A fast, stylish DS branch worth playing once you know you like 2D Sonic.
Famous, but mostly for being unfinished and frustrating; keep it as historical context.
Sonic GenerationsStart here
A strong sampler of both classic and modern Sonic, especially once you have seen a few originals.
