Question for you experienced vita owners. I just picked up one of the bundles from Amazon and need to get a bigger memory card. About how many games will fit on a 16GB card? I plan on keeping plus and I see uncharted is just over 3GB but I assume game saves, ect take up space too. I'm guessing 4GB per game is a good size one game so I'd get about 4 games per 16GB card?
