It's relevant to you because it helps your arguments. To everyone else: not at all. The "socially accepted" idea is that when comparing franchise sizes you compare the selling power of each game in the franchise, not total sales.
Oh please. The significance is there nonetheless, regardless if it helps my argument. Flagships are symbols of the console itself so they inherently need multiple games per gen. And they must be top rated in quality. Halo 3/Reach and Mario Galaxies got over 90 on metacritic where as GT5 is an 84, and took 5.5 years. That sir is no flagship. Uncharted is cause its quality is 90+ and it releases more frequently, keeping the fans happy and not waiting long.
Older and wiser. Still bias and proud though ;)
