What aspect do you think Nintendo should be focusing on improving the most right now?
The gameplay in their games
The presentation (graphics, music, etc.) of their games
The quality of their game systems.
Their online services.
The availability and accessibility of their products.
The rate at which they come up with new games.
Their merchandise and media beyond video games, like manga and films.
Their communication and cooperation with content creators.
I have no opinion on what aspect Nintendo should be focusing on improving the most right now.
