RetroGaming

I disagree but only because I've seen it showed to me by my friends who are super into this. When games were made for TV and consoles especially in the late 80's and 90's they did things that took advantage of the analog nature Cathode Tubes used to display the image. Not every game took advantage of these techniques but the ones that do are nothing short of amazing when you think about it. They make filters these days that emulate some of these effects but analog is still analog and isn't something a digital display can always emulate regardless of resolution. I would say for most people it just doesn't matter that much but if your a retro gamer you want the OG experience. It's difficult to emulate these analog techniques because they are specific to an era and the techniques can sometimes be unique or trial and error by the devs.

There are other things as well for example light guns which just straight do not work on a newer display. Games that had live action recorded video look hilarious because the same techniques that were used to make things look better were applied in make up form to the actors.

What is a bit sad is the specific techniques these developers used aren't being well recorded and documented which I think would be very useful for future emulation and filtering.
