That's an urban legend. The government did tell Enix not to release Dragon Quest on school days, but it was a tongue-in-cheek request, not an actual law. That was said in the context of Dragon Quest III, which was incredibly huge for the time (it took ten years for another Dragon Quest game to become more popular), but has since been beaten by other things.

Final Fantasy VII (Most popularity): 3.3 million Japan, 9.7 million worldwide

Final Fantasy XIII-2 (Most recent): 0.8 million Japan

Monster Hunter Portable 3rd (Most popular): 4.7 million Japan

Monster Hunter Tri G (Most recent): 1.2 million Japan
