PS Vita: Deathmatch Village (PS Vita version) - My Singing Monsters - Treasures of Montezuma Arena - No Heroes Allowed: no Puzzles Either.
PS Mobile: Adventure Bar Labyrinth - Sword of Rapier
Vita Apps: CrunchyRoll - Crackle (I am sure there are a LOT more but I'm not one to do a lot of media on my Vita and I despise social networking such as twitter and facebook. I also noticed you have Netflix on there. I wouldn't count that as free since it requires a payed membership, unlike Crackle and crunchyRoll)
