because games nowadays take up to 40gb+ of space and I dont just play one fighting game, I like to play all of them depending on what Im feeling.
If I were to try to put them on one console they all wont fit because theyll take up too much space and say I if want to play a game that I deleted because of lack of space I would have to wait until it finishes downloading in order to play again.
Also I think Rainbow Six Seige is almost up to 100gb now and also CoD Warzone takes up a huge chunk of space. Final Fantasy 7 remake was also 100gb I believe.
I just like the convenience of switching up fighting games on the fly and not worry about deleting them and re-downloading when I want to play them again.
I dunno maybe Im just weird.
This is why spouse got a 1 terabyte external storage unit for their PS4.
