When the N64 launched I could not wait to see what they were eventually going to do with Yoshi. I wanted to see Mario 64 Yoshified. When Sunshine hit I really loved the way Yoshi handled and I just knew they would take that as a base for a solo 3D outing. Years later when Galaxy 2 released I really really knew they would take that Yoshi as a base for a solo Yoshi game. By the time Odyssey came around all faith had been lost, Yoshi would only ever have 2D and 2.5D games for the foreseeable future. The best we could get were the amazing power ups he'd provide in 3D Mario titles. Yoshi in Mario 64DS wasn't so bad but not what one might call full on Yoshi gameplay either.

Doesn't this just look so inviting?!
Anyone have any idea if Nintendo has ever expressed interest in a fully 3D Yoshi title? Any interviews floating around from ages ago? There is so much to work with from the Mario series already I am surprised Yoshi hasn't been fleshed out more in a 3D setting.
Beyond fruit or magical power ups, Yoshi's design has so much gameplay utility just built in.
Yoshi's tongue does so much and it has always been so fun to utilize. Sunshine made it extremely long, homing in on enemies and fruit. Galaxy 2 allowed us to point it manually and depending on what we grabbed it would tether him forward and swing like Samus' Grapple Beam. In Odyssey it worked like the Hook Shoot! It felt so good to slurp the walls back and forth sticking for a moment like a weird chameleon Spider-Man.

Like Mario, Yoshi could Triple Jump and Spin Jump and of course the hovering allowed for a little cushion when platforming.
Fruit was always fun in the 3D and 2D games. Spit seeds, fire, ice! Chili's would have Yoshi running up walls and those funny blue berries had Yoshi taking his own version of the P-Balloon. Does no one else long for more of that but expanded significantly?

And then of course there are the eggs! Only Mario 64 DS gave Yoshi projectile eggs in a 3D setting. Super limited but it was nice to see. I want a 3rd person shooter with Yoshi! I want to toss those things left and right bouncing them across walls and using trick shots for puzzles. Skipping eggs across water and nailing far off enemies right between the eyes always felt good. I have to imagine it would be a significant step up for the series if given a try.
Yoshi's Island was given A-Team star treatment back in the day, you could just feel it! As a kid there was nothing I was looking forward to more than 3D Yoshi and 3D Donkey Kong. With each generation it just felt like solo Yoshi would just be continuously handed off to the B-Teams. That isn't to say that Wooly World or Crafted Island weren't very enjoyable games, I just would personally love super ambitious 3D outings to go alongside the safer 2D types.
If we can have watered down Yoshi gameplay in 2D Mario titles side by side with full on 2D Yoshi titles, there is no reason the same can't be done for 3D. Mario, Zelda, Metroid and now Kirby both have 2D and 3D options. 3D could really give the Yoshi IP a boost, I just wonder why it hasn't been done yet. Maybe with the success of Forgotten Land, other studios at Nintendo will consider making the 3D Jump.
