I'd suggest a D9P, fast and easy. I would use your games fabric for the corner blocks, one color for all the center blocks with a pop of brightness or a very dark, depending on the colors in your prints. And interesting coordinating prints for the squares that will be cut into rectangles. Tone on tones as well as geometric prints would work, so would solids.
I made one for my grandson in green scrappy and he loves it still.
