Back when you had to have memory cards to save your data. And the memory card was 1 MB.. 1 tiny MB which held a ton of save data for your games. But I have to admit it was pretty cool when PS2 came out with the memory card holders in their game's cases. And PS2 had 8 MB of data on their memory cards. 8 times the storage space! That was so much data back then haha. Now it takes 30 GB on average just to install the games on your hard drive.
p.s. nobody gives a crap
I own nearly every Playstation console
