Yeah, I'd call Mario Odyssey the Mario version of BotW, massive worlds, tons of exploration, way too many things to collect. There are more things to collect in Odyssey than Korok Seeds. XD
It's super fun. If you liked other Mario games, I'm sure you'd like Odyssey. It's not level-based like 3D World. It's more like Mario 64, and less like Super Mario Bros.
Drill Dozer is quite old, so it's unlikely you'd see it for sale anywhere in person, but if you have a GBA and not a Wii U, then you can probably order it online. If you have a Wii U, it's much cheaper on there.
