Shadowgate and the other MacVenture games were black text on a white or beige background but they were originally Mac games so that explains the design. Final fantasy was white on blue. As was Crystalis. I suspect the reason it's not more common is the NES pallets sharing a color for color0. You can use black to indicate lines or shadow depth on basically all objects, whereas white is less universal.
