Which type of Games does Vita need more of?

[forevercloud3000]

So in conjuction with my other thread asking why many do not have a Vita, I would like to hone in on one of the answers "It needs more games".

Pick the type and genre that would most appeal to you on Sony's handheld or the one you simply feel they don't have enough invested in to attract gamers. Then discuss the specifics of the game types you are most interested in seeing.
