Final Fantasy III for Android is my all time favorite.
Eeee but it is expensive though, R132 .But worth every penny since you will be playing for more than 20 hours anyway, plus they changed the graphics to 3D and made it more fitted to mobile.
The final boss , The Dark Cloud ( or something like that )has been upgraded since DS version and is more difficult to defeat.
I've been playing this game on-off for a while now - mostly on flights between Joburg and Cape Town.
It's engaging - well layed out with a great story line.
You basically scavenge to survive in a war torn neighborhood. The game is set during a conflict in a fictional nation. You control three survivors trying to survive in a dilapidated building. You start in a war damaged house that's mainly filled with rubble and a few supplies. During the day you work and sleep and eat. During the night one of you has to scavenge.
You control 3 individuals. You interact with the game by tapping on it. You have to search places, fix, and create new things with the items you find. During the day you build and make your home "safe", and during the night, you pack your backpack with items and go scavenge for more to survive.
This game reminds me of Commando's on the PC in the late 90's. It's a great game, but I find that a 5" display is too small to play comfortably. It's clearly been a PC port. Larger devices or tablets would be better suited to this game, although I've clocked a number of hours on my Galaxy S6.
It ain't cheap, so wait for specials. Often there are 50% off deals on the Play store. It's R70 otherwise.
