Especially good if you have some vision problems. It is good to play videogames on big screen, will it be a monitor or TV screen. Can you imagine - using a laptop with 1,5GB RAM storage in 2020? It's even not a 2GB RAM storage! It had a very weak processor and very, very weak graphical processor(video card). I had a laptop with 1,5GB RAM storage and used it from 2018 to 2021. Not everyone have at least just WEAK computer/laptop to run Steam and games on it.
Yeah - playing videogames on regular Nintendo Switch in handheld mode while having vision problems is not a good idea too, but I don't have options to play it in TV/docked mode. Because of this, playing JRPG games on smartphone is not a good idea for me. Rarely(?), some JRPG games requires a fair amount of time for grinding. And I have some vision problems, so I can't play videogames on my smartphone for a long time.
I have only Nintendo Switch and Android OS low-cost smartphone.
