The franchise is very much split in gameplay style between the 2D and 3D entries. Generally the 2D games are much more highly rated, but there are good 3D games (and not-so-good 2D games) too. Here’s a list of what’s worth checking out of each:
2D
The original trilogy from the Genesis (found in various Genesis collections and Sonic Origins)
Sonic Advance trilogy (GBA)
Sonic Rush (DS)
Sonic Mania (any modern console and PC)
3D
Sonic Adventure 1 and 2 (Steam, modern consoles MAY have digital copies)
Sonic Colors (most easily accessible through recent remaster on PC and modern consoles)
Sonic (X Shadow) Generations (just remade everywhere)
Sonic Frontiers (haven’t tried it myself but heard it’s alright)
