Personally, I think that 2D gaming still has a bright future. From my perspective 2D gaming has its own advantages and it attracts me a lot. I especially agree that 2D gaming is a better way to create a world with strong artistic style. First, I think hand drawing and 2D is a comes first when we try to do something conceptual and creative. And 3D games tend to be kind of dull when it comes to modeling thus it can’t emphasize a world with many features. Instead, in 2D games (like some dungeon games), the combination of different culture and transition between two different scenes can be really natural and attractive. 

Also, 2D games is really easy to be familiar with, and because of this, it usually demands the user to be really skilled with the basic ability of the characters to pass the game. This gives player a very exiting challenge which I love a lot. And because of the limit of 2 dimensions, the moving of characters become limited. Game designers need to create many interesting interactions or ways to play to enrich the game. And it leads to some fantastic gameplay mode. Like the image based interaction in Rusty Lake series and the hardcore platform puzzle solving in Celeste or Hollow Knight.
