I somewhat agree with you, except, GT6 should have sold more, but the franchise is in decline. GT 1 and 2 and 3 were the best selling games for the ps1 and ps2, selling double digit millions. Where as the past 3d mario games have only sold tops 5 million each. Mario is a larger franchise, however GT6 is a larger franchise than 3D mario specifically. And install base really is important to take into account though. 3D world has a great attach rate where as GT6 does not.
