This achievement can easily be obtained by idle boosting if you have a partner.
Easiest way to set this up is to
Play with friends
You only need one other person and when the game ends it wil automatically start a new game after a minute.
As a side note you have to make sure that if you idle boost this that you need to connect your controller to a charge cable so it stays on and make sure you are on the games screen and not the dashboard because this will pause your screen and after a while it wil disconnect you from the game.
Using this method should take around 33 hours to do when starting from 0
And while you are going for this achievement you are also making progress for the 500 classic games achievement so it's two birds with one stone.
Sorry for probably some misspelling any corrections would be appreciated
