I would LIKE to do the same thing, but I find it really hard to justify the investment unless I could get it for $70 or less.

As a Vita owner I can promise you this is not necessary.  All you have to do is copy and paste them to your PC or PS3.  You don't even have to redownload them when you want to revisit them.  I would recommend going with the 8G and buy several good Vita games instead of dropping the money on the 32.  Just my opinion.  Only reason I could see claiming this necessary is if you game a TON, like all day and mow through games, or don't have readily available access to a PC / PS3.  If you're going to play 6+ mid to large sized differnet games on a given day you need it, If anything less you don't.

Yeah, we were talking about that earlier.  What I mean is that ideally, I would like to not have to juggle my library.  I might have to, though, if I want to save money.  Personally, if I were to juggle, I'll do it with 16GB rather than 8GB.  If a single game will easily make up nearly 1GB, I would pretty quickly have to start doing this.

I have a 16gig card and currently have 11 digital games on it (though some of them are smaler psp games). If you don't plan to go full digital it should do the job and you can always back stuff up on the pc or redownload. Most full vita games are around 2 gigs as far as i know.

The only thing is that if you don't have ps+ and the cloudsave that comes with it you'll have to back up the whole game on pc/ps3 before deleting it to keep the save and the transfer can take some time (only with vita games psp and psone saves can be backed up seperately (but can't be sored on the cloud)).

LittleBigPlanet PSV
Rayman Origins and Legends (coming soon) (If you haven't played Origins yet)
Mortal Kombat
Uncharted Golden Abyss

And there are a whole lot of PSOne classics on PSN although you would get the whole list only on PS3, i think.

oh and if you're going to look into psp games i'd highly recommend half minute hero

Well, there are a lot of PSN titles I want to get, so I'll most likely want a 16GB memory card.  However, I don't think I'll download original PSV titles considering how many PSN titles I am considering.  It would be easier for me to just get the physical copies.

Then 16gigs should probably be enough. Have fun playing and if you need someone for an online game or stuff you should drop by the official vita thread.

Oh hey one other thing I thought of that is a little off topic. It is worth looking on ebay or places like that before going to Best buy and whatnot. A friend of mine recently got a Vita with 2 8GB cards, a charger, a case, Madden 13, and Wipeout for 160 bucks off ebay that functions perfectly and looks like it was never even turned on...

Buy all the Games (except Cod)
