There is a variant of that silly "rule" that goes on, ItsaMii. A product which pioneers a particular set of values will stand above those that imitate it, and this dominance usually continues for at least 10 years. The split there actually usually is 80/20 or close to it at first, eventually evening out around the 10- or 15-year mark at 50/50, then going into decline. This applies to all products, not just games. 10 to 15 years is roughly how long brand loyalty can be counted on for disruptive and blue ocean products.
