Why 3D in a 2D game makes sense
The reasons we want to use 3D models in our 2D scene include the following:
- Recycling of assets: You can use the same models as used for a 3D game engine project, as well as countless others.
- Broader base of talent: You'll be able to use a 3D modeler for your 2D game, as good sprite artists are so rare.
- Ease of animation: Good animation with sprites is hard. With 3D models, you can use various existing utilities to get smooth animations with ease.
As for the final impact it has on the game's looks, it's no silver bullet but should ease the development somewhat. The quality of the used models and produced animations as well as the way they are integrated into a scene will determine the final look.
