A side from the recent ones?
Sonic Jam on the game.com
Farty sound effects, hard to see whats going on, short.
Its a sequal
If Sonic was playable it would have Sonic in the title.4. Shadow the hedgehog (it was too easy and you could only play as shadow they should of atleast made sonic playable)
It wasn't when it came out3. Sonic Spinball (it was cheap and bad graphics and luck)
I assume you mean Sonic on the Game Gear?2.Sonic the hedgehog GameGear (no point honestly the SG was better)
By talking about the Game gear one you must also talk of the Master system one as there almost the same game and they both are good.
By SG I assume you mean Sega Genesis?
Stop being lazy and use there full names.
