well next to gameplay the most important things of a gaming ip is its atmosphere, characters, and music. banjo still has all of those and i actually really like the main city u see in the trailers. Final fantasy being the big exception here
im pretty sure there will be a racing level or 2 in the coliseum. levels like that usually mix up the pace and are in most platformers
its adding good co-op, online multiplayer, and making the platformer genre less linear so u have to credit them for that
