I don't necessarily believe we need a game filled with them. However one where they do take a prior role of the game. Legendary dinosaurs, dino trio, etc. And where maybe set during a period where not all are extinct but many are, that could allow a nice mix between ancient pokemon and normal.
I just feel their is untapped potential that isn't used because they are so situationally added to games. And it would be cool to see like more pokemon based off of a T-Rex, Stegosaurus, Triceratops, etc. Especially if it was before they were fossilized so it could explain why they aren't rock type.
The game could take a safari feel, jurassic park almost.
