I'm on the lookout for an RPG for Android to dip in and out of on the train. I don't want an action-RPG, good old fashioned turn-based will be better I think for the times I would play it. I also want something with a story that has a definitive end. I don't mind paying something if it's good, but I have no idea what is out there. Not fussed about the setting, but some depth to the mechanics are a must. Recommendations?
