Honestly, I hate the CRT aesthetic. I grew up with CRTs. Leaving them behind for LCDs was one of the greatest transitions of growing up. By all means, enjoy them if you do, but I don’t.
It’s not just the look of it, but the art and games were designed with the limitations of CRT in mind. Not all games off course. An example is the transparency effect on Genesis / Mega Drive:
Shaders are not only useful for CRT emulation, but also to get the look of handhelds:

Does this shader also replicate the horrific motion blur that the display of the original GameBoy suffered from?
