PlayStation Vita. Apart from requiring a memory card for PSN downloads, many retail games have their own storage requirements as well. After the break, we've listed the requirements for every retail title we have on hand (see image above, Rappy included for scale). We've also included the storage required for the downloadable Vita games available thus far.
The retail games we have add up to just over 255MB of required storage, a figure you might want to keep in mind before deciding which incredibly expensive memory card is right for you. It's also worth noting that a full 160 of those MBs are dedicated to FIFA Soccer.
