Oh good. 
Create new layer (ctrl-shift-n), and paint in all the cracks by hand with the brush tool set to ~10 point and 0% hardness. Then when all the lines are drawn, use gausian blur with a radius value of ~3 pixels to blend it in and soften it.
How well does it tile in game? It didn't tile very well when offset in PS.
