Didn't mean to completely shit on the sale. There's a few decent games in there that are well worth buying. In my opinion, these are:
LBP Vita- saw the thread's discussion on it. I bought it as my 1st vita-exclusive game and the game is very fun, but there are aspects that get annoying, like the damn flying object level where you have to use the rear touchpad to tell it where to go. That gets irritating quick, but at least you don't have a limit how many times you die before the game ends.
Lumines Electronic Symphony- addictive puzzle game, but once you beat it there's not a ton of incentive to keep playing it. At that price though, skip it. I'm surprised it's still that expensive!
Persona 4 Golden- The reason to own a vita! By far the best game I've played on the system, the story is interesting, the side quests are fun, the combat is pretty easy to grasp, graphics look great... Amazing game, worth it at any price!
Tearaway- ok game, got kinda old fast though. Didn't really care for having to draw my own objects and kinda hated the front camera being so active.
