OK all the games that I have under the tree are GameCards. But when I put them in the Vita since it is a gamecard will it download to the 16 GB memory card? Because I have like 6 games that I am getting.
With physical copies of games (i.e. Game Cards) they only install system data necessary to launch the game as well as any updates for the game such as game patches or DLC for the game. I believe your game saves are also placed on the memory stick.
I've had a 16gb since day 1. I only own 2 physical games and the rest are digital. A 16gb memory card should suffice for most people unless you plan to download a lot of movies. With my digital games I delete them after I'm done with them.
