1995 during the SNES era we played games in 60fps, so playing games in 30fps in 2019 is clear step back to me.
I understand that making a more powerful console would increase the price and therefore lessen its mass appeal, but man, I can't help but noticing that the latest Zelda, Fire Emblem or Pokemon games look like PS3 titles from 10 years ago and keep wondering what they would look and perform like with state of the art hardware power.
I don't care about graphics; I am very happy with Ys 8 on the PS4 Pro (running in 60fps makes a huge difference); but I care about image quality, which includes framerate, and BotW for example is a mess in these areas.
I would be perfectly fine with Pokemon Shield's graphics if it ran in 60fps, but who am I kidding.
Long story short; better framerate makes every game better, and that does count for Nintendo games, too. I can't help but wonder what Breath of the Wild in 60fps would look, play and feel like.
