Why do all of the Maple copy cat games keep dying?

There really hasn't been many copycats I am aware of. And the ones that "were" copycats didn't capture the same essence. I found a lot of them lacked the customization for looks, a solid art style, and most had bleh gameplay in general.

We really are lacking quality 2D MMORPGs and it's a shame. I don't like the awkwardness of 3D games (the camera, movement, and it just doesn't feel fun or even welcoming to me.) I don't know why people instantly assume 3D is better.
