My friend says he has about 12 games there so far and isn’t to 50% yet. Most games are 1gb or so according to google. But that depends if and when they come out with some triple A games. On PS most games are only a few GB. When you DL a game like Call of Duty that jumps to about 60gb. I’d say 128 hits the spot for 1 actively played game or 2 that’s bigger, and a bunch of indie games. You can always re-download later.
