This is just what happens when you're interested in things that aren't too popular. Yoshi isn't very popular among the older gaming demographic, even though his games sell pretty well. Similarly, very few people were excited for Dark Samus when she was announced, and not many more are clamoring for a new Chibi-Robo game. And ain't nobody remembers my boy Dimentio.
It's tough liking things that aren't that popular, because then it's hard to share your enthusiasm with others. I was freaking out about Dark Samus last year, but very few people online were partying over that specifically. Everyone was marking out about Simon, Richter, Chrom, and K. Rool, and I and only a small handful of other people were primarily excited about Dark Samus. All my closer friends/family had no familiarity with the character, so to them I just came off as an insane person.
If it makes you feel any better, your enthusiasm for Yoshi has rubbed off on me, at least. I've never bought or played a Yoshi game before--never paid him or his games much attention--but I plan on getting Crafted World. Gonna try out the demo this weekend
