In Blender, "Baking" is a way to pre-render some part of a scene, so that future renders are faster. You can also bake features from one object onto another.
In this case I'm using it to create a good-looking low poly object from a high poly object.
1. This is the low poly quarterstaff before applying Texture or Normals baking. 118 polys. 2. This is the high poly quarterstaff for comparison. 752 polys. 3. This is the low poly one with the texture and normals from the high-poly one baked in. 4. This is the high poly object. I use simple procedural texturing.
Staff #3 would be the one used during gameplay, and #4 might be used in a still render or a cutscene.

Thanks! That's the exact look I was going for with the wood, and I'm surprised it came out well. The technique in Blender to make that is incredibly simple (Fractal then Decimate).
And I agree with qubodup, great comparision
