Q:

Using the face edit mode as a texture in bge

In the blender game engine, is it possible to make it look like this when you actually play the game? 

Obviously, this was screenshotted outside of the game player while in edit mode, so maybe it's possible to bake this texture to an actual texture which I can apply to a material? 
This is very likely impossible though, so maybe theres a script someone made to generate the texture for each face? ( so for each face just a simple light grey texture with dark grey outlines?) 

A:

I have arrived at an imperfect approximation.  It will create the effect, but has some flaws:

Edge lines will be inconsistently thick. 
Center point may not be exactly centered. 

However, the result is definitely passable:

To create this, you need a few steps:

UV unwrap it.  You U>UV unwrap
Reset the UV's U>Reset
Add an image texture, I used this image:

Set the UV map

TADA!  You have your result! 
See the .blend for any confusing details:
