To continue that analogy. I absolutely love boogie boarding(D&D RPG), but I dislike standing up to ride waves(most other RPGS). Even so, I know that there are different brands of surf board. Some have 1 fin, some have 2 fins, some 3, 4 or even 5. I know they come in different lengths. I'm not ignorant of surfboards or surfing, but I'm also not an expert.I would posit the two generally go together.
I'm not interested in surfing. Because of that, I am unaware of any particular surf boards, or surfing associated brands.
I do like other RPGs by the way, just not any of them more than D&D. My players are the same way. I think it's presumptive(arrogant) to assume that D&D would be 2nd, but popular if folks weren't ignorant of other RPGs. I'm sure D&D is 2nd or further for a lot of people, but it's also 1st for a lot of people.
