I still only have an 8 GB card for my Vita because I'm waiting until the 64s are released over here (ridiculous how expensive these goddam cards are) but I'm just wondering how much space I'll need to free up on my card to install and play X-2?

If you look on the PSN store the exact amounts required to install FFX and FFX-2 are listed. :) I can't remember the exact number, but they were almost 5gb each.

@meatball: Actually I tried that earlier and it's only showing up how much space I need to save a game. The actual game sizes aren't listed which is super unfortunate. I'm also on the German PSN store so it might be different in different countries, but here they don't show sizes. I've had this issue for other games too, it's really annoying. You'd think they'd include it.

I can find the sizes for the NA version (which I would prefer to have but can't get :| ) but the exact european sizes aren't listed anywhere on the internet, that I can find.

Whoops, you're right, I misread KB as MB, I feel incredibly stupid. I just bought the game, though and FFX-2 is 3413 MB (and FFX is 3402). That's in Australia, but I imagine we get the same version PAL territories/Europe do.
