The only good ones are the ones where you can play with rooted phones and crack. Such as Genius! games and D3 Publisher like Twilight Hunters or Sengoku Princess.
There's also an exercise app/ otome game called burn your fat with me it also works with rooted phones with the lucky patcher and its quite nice to exercise to Namikawa Daisuke's voice counting your crunches and calling you a fatty at the same time <3.
Edit* It seems Genius! Inc. has released new games and they look quite promising than the last ones and there's even one that's suspense and VOICED.
maybe like a zero escape vibe and note that it can still be patched via your phone.

I must say though some of their localization titles are a bit off and just gaudy but some are okay, at least the game's story translation is more or less correct and interface reminds me of quinrose games.
and i do love the fact its not those dress-up BS apps like Voltage or Arismatic craps out.
