It’s Toy Story, but by Sega!
Released as a US Sega Saturn launch title, Clockwork Knight is a 2.5D platformer that combines 3D polygon worlds with pre-rendered CG characters for a unique look. The game stars a toy soldier called Sir Tongara de Pepperouchau III who must save the Clockwork Fairy Princess Chelsea who has been kidnapped. You must use your key sword to battle various other toys who have been manipulated to stop you from saving princess Chelsea.
The game has only been released on the Sega Saturn with a sequel released on the same console so playing it today would be somewhat difficult. That being said, it’s worth checking the game out, if you can, to see what Sega platformers that aren’t Sonic are like.
