If a big budget shooter comes out, people get upset that yet another game in this genre is coming out. if the art style contains a lot of gray and brown, they groan even more and call it generic. If a 2D indie platformer is announced, people act like that's a sparse genre and herald it as the beacon of true creativity. If the art style is pixel art, it's praised as being the most original and unique thing ever made.
How come making games in a flooded genre with a generic art style is loathed in big budget games but praised in indie ones?
