[quote name='mark_IV']I don't own a Vita yet but I've been "purchasing" the free games with Plus. Roughly how many full Vita games (not minis, etc) would a 16gb card hold?[/QUOTE]
i have a full 32g (not 16). it has 660mb free, and i'll need to delete stuff to grab disgaea 3 and future ps+ releases (which is never fun, i already deleted some ps1 games, lol, as well as games i've beat).
It currently has (all dls from the store):
5 'big' vita titles (sly, oddworld, all stars, rayman, gravity rush)
16 psn vita titles (along the lines of sine mora, super stardust, lumines, dokuro, pinball, etc)
2 vita demos
4 psmobile games
8 psp games (valkyria chronicles 2, disgaea, etc)
14 ps1 games (ff, etc)
17 minis
and several apps like netflix, sony music unlimited, youtube, etc.
so... roughly divide that in half for a 16.
games like sly and uncharted:ga are like 3-4 gigs. oddworld and rayman are closer to 1-1.5. super stardust is 215mb, sine mora 672mb, lumines 755. so it's a wide spectrum... but it definitely adds up, especially with ps+. heck, even ps1 games are generally 200-400mb.
oh, and since you mention you have ps+, i'd say you already have enough games to warrant grabbing a vita when you can. just the ps+ games alone have been fantastic.
and finally, just fwiw, if they sold bigger than 32 i'd do my best to get one. my library only grows, especially with ps+.
