Disgaea 4 originally came out for the PS3 back in 2011. Like Disgaea 3 Returns, the new PS Vita version will come with all the DLC released for the PS3 game.
Criminal Girls was released back in 2010 for the PSP. The game was developed by Imageepoch and published by Nippon Ichi. Sadly this title never saw the light of day outside of Japan. Lets hop Criminal Girls INVITATION for Vita has better luck.
