I strongly disagree with the premise that there's a "wrong" way to play retro games. Don't gatekeep. Imagine if people told you not to listen to Pink Floyd unless it's on vinyl. It would be lost media.

That said, CRTs present images fundamentally differently than LCD displays, and a lot of developers took advantage of those idiosyncrasies. There are scanlines everywhere. CRT phosphors aren't square, and appear smaller when darker. Bright pixels can "bleed" into nearby pixels, particularly when using composite signals.

Before LCDs, many (not all) pixel artists used this to their advantage, basically harnessing the imperfections of analog TV to provide equivalents to anti-aliasing, bloom, extra color depth, and even transparency. Some particularly famous examples came from Sega Genesis games. This video goes into good depth on the whys and hows, and there are some solid examples of the outcomes here.

I've attached examples below (hopefully they upload). If you like the raw pixel art, then no harm done. Enjoy! But if you like the way CRTs interpreted and filtered those signals, you owe it to yourself to look up some shaders for your favorite emulator.

If people like using them, more power to them, but as someone who grew up playing on CRTs, if I could have had crisp pixels instead back in the day, I would totally have chosen that.

No, I don't need it.

There is no world in which anyone ever designed a game for anything more powerful than a Gameboy where they expected people to see it as a seemless grid of squares so big you can see them from across the room. That's just not a real thing outside of badly designed modern "retro" graphics. There's a reason for that. Seemless square grid is ugly. Like, disgustingly hideous. I do not understand why anyone would ever want to subject their eyeballs to the atrocity that is giant square pixels. If you want to do that to yourself then I can't stop you. There's no accounting for taste and all that, but just know that I think less of you for it.

Wow gatekeep much?

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.

You'll never catch me using filters like these voluntarily. Inject those crisp pixels straight into my vein.

My aim was never to emulate but to play. Blur filters are something that I won't be using.

The benefit of CRTs is most apparent in pre-rendered backgrounds (See Final Fantasy, Resident Evil). These backgrounds look incredible with shaders, and, indeed, on real displays.

Good looks stay good.

If there was a good crt shader I'd love to use it. Haven't seen any good ones yet.

No and no. Clickbait bullshit.

Real. Ever since I spent some time setting up good CRT shaders, playing retro games feels a lot cooler. They just give the best feeling and look pretty nice with them on. Sometimes for fun, I leave the shader on for regular Windows usage.
