External memory card required for some Vita titles

The hidden costs of picking up a PS Vita are starting to stick out; it’s been revealed that some of the handheld’s titles will flat out need an external memory card (the type not included with the system) to be played.

Any big games, one asks? Oh no, just a little something called Uncharted: Golden Abyss. Oh.

Apparently these games won’t even start up if you don’t have a memory card to back them. Initially we’d though you just wouldn’t be able to save those games, which would have been enough of a problem itself.

Have these extra costs dissuaded you from picking up a Vita?
