Don't let this thread leave the front page. They need to optimize the Vita file size. It doesn't need to be this big. They just keep adding stuff on top of it without rewriting some old stuff. They should re-release the entire game or make sure that each patch doesn't take up close to a gig.
Please if you have twitter teweet Seth Killian and Sony Santa Monica. This is a serious issue. We could be sitting at 3+ gigabytes soon.
Try deleteing the game data/update data then downloading the patch. Like a post said above, some are saying the last patch appeared to overwrite the patch before it, so it's not a net new 800mb.
