PS4 seems to have a faster downloading time than the Xbox. The Switch seems faster than those though.
Cartridge days were awesome. Even up to PS2 wasn't bad. Insert the disc, and play. Data saved to a memory card. When the memory card was full, put in another one.
I had to get a 3TB external HD for the Xbox. It is almost full, and the PS4, I need to get one for it as well. 500gb don't go far. Especially with all the updates that continuously come out.
