The power difference will be to much that any games on the next xbox and ps5 won't be able to be ported to the switch. causing bad 3rd party support in the future.
Well when games look so much like real life and can't get any better we will be able to use the same hardware forever with out upgrading and gaming will get much cheaper. since the hardware will no longer need to be upgraded it will get cheaper and cheaper hence making gaming cheaper since...
You don't have to play them but i feel like i'm missing out if i don't but they do make me feel stressful because i feel like i have to spend a ton of time on games.
I do since the switch doesn't have pokemon and some other game series yet it also does not have backward compatibility so you will still need to play your 3ds anyways to play the older games. Which is why I think the 3ds is still alive and won't be discontinued anytime soon.
