For an android text based / choose your own adventure type RPG: A Choice of Broadsides
It explicitly draws from POB and I'm far from the first week has made an Aubrey and an anti-Aubrey prototype.

If she likes reading, she may enjoy stuff made by Choice of Games, or Hosted Games.
Basically, multiple-choice choose-your-adventure novels. No pictures. No sound effects. No music. Just reading and making choices. Example.
You may want to screen through the selection to find age appropriate stories.
You could try www.choiceofgames.com (they have apps on the Play Store). Choice of Broadsides and Choice of Dragon are free. There are plenty others. They don't use much battery either.
Anything?
>Edit: Sorry forgot to say this but I'm looking for emulator/rom suggestions
Sorry, can't help you in that regards. That ~~tablet~~ phone uses Google Play Store, correct?
If you don't mind reading, than the multiple-choice adventures created by www.choiceofgames.com might catch your interest. Also Hosted Games is another, similar, developer. Plus, these games won't kill your battery.
Some of my favorites:
Choice of Broadsides (free)
Choice of the Dragon (free)
Mecha Ace (not free)
The Lost Heir: Fall of Daria (not free)
