That was the main reason I got an Xbox, the constant upgrades needed for PCs to run the newer games was really annoying me!
I think what they did with the Wii was quite incredible out of the box stuff which pulled them right back into the console light whereas is they tried to directly compete they probably would have bombed
I've not played much with son's PS5 and Switch, but the latter has versions of things like Wii Sports and Mario Kart that look similar to the Wii. Nintendo were always good on playability.
They totally were. I am trying to convince the kids a switch works be a good family investment just so I can pay Mario kart again!
