Metal Gear Solid is a part of the Metal Gear series. Considering only two main-series titles released in the series without the "Solid" titling, you can hardly distinguish them from each other.
And I've stated a dozen times - franchises listed were selected based on sales and popularity. Every single franchise you just listed has minuscule sales in comparison with most the other series' included. And if their sales do compare, their level of popularity hardly does.
Honestly, now. I can't list every remote franchise that exists or else I'm going to be listing over three-hundred selections. I have to draw a line.
