This discussion of quality pops up for different things like music, photography, print, too.
As an example: Audiophiles will state that you need certain equipment and the music has to be compiled in a certain way (fidelity/compression) for it to really shine and be enjoyable. The majority thinks otherwise or just does not care enough and this is why we have MP3 and certain compression which is 'enough' for many, but not really ideal or even good. I looked up an article about that topic:
http://saportareport.com/leadership/technology/2012/07/24/audio-fidelity-and-the-return-of-vinyl/ and I thought to myself...
"Mabye the crowd who will invest in sound equipment and rally for things such as the High Fidelity Pure Audio format to replace shitty MP3s is the equivalent to the crowd who will invest in a state-of-the-art computer to play the games at higher resolution and 60 frames per second."
I'm in both crowds. I care for music and sound quality, and I care for image quality. This was not always the case for me since I was so used to bad compression and bad framerates that it took some time for my brain to adjust to the obviously better quality. Listening to certain music with the right equipment and format vs. listening to the same music with MP3 and computer speakers... it's the same as playing Bayonetta on PS3 vs. playing it on Xbox 360.
Now I think it's obviously expensive and a hassle to get good audio equipment (it took some time and years of saving for me) so whatevs. But when it comes to gaming, one already kind of has the right eqipment for 60FPS with a HDTV and a state of the art console! I'd rather have developers concentrate on giving us 60FPS instead of giving us 11 explosions and 5 million particles. I also don't see why the "Can't see the difference"-crowd seems to be somehow against 60FPS... I mean, OK, you can not see the difference but many other people can so why be against it if you would not even recognize it? Though yes, not every genre needs it at all costs, that much I agree - adventure games, RPGs, hey even many of the cinematic action games which nowadays basically play themselves anyway. But every game which needs at least a little bit of timing or reaction is just better with 60FPS, for me at least. 30FPS is not "unplayable" but I would avoid any Arcade-style shooter, fighting game, racing game or even competitive FPS/TPS with 30FPS and lower. And it really is sad if it is unavoidable. I'm hoping for Last of Us PS4 to deliver..
edit. god reading what I wrote again, I really sound pretentious. Sorry about that :/
