Choosing Floor Tile

On 8-bit Nintendo, there would be no lighting effects.

Sprites would be drawn to fake things like shadow and depth.

Modern games have bump mapstextures that add depth and detail, and interact with lights in the scene.

How much modern detail do I want in my game?

Left to right, I have an unlit texture, a lit texture with shadows, and a lit texture with a bump map.

Which would you choose?
