Inpatient - interactive fiction about being in a psychiatric ward, damn good writing, very immersive and fresh http://www.inpatientgame.com/
Heavy Metal Thunder - Action Sci-Fi, kind of a pulp fiction with lots of fighting, but the flow and immersion are cool. Hard choices, scarce equipment and skill slots. Also nice UI and ambient sound. https://play.google.com/store/apps/details?id=com.cubusgames.hmt
Tin Star - excellent western interactive fiction, massive scope, RPG elements https://play.google.com/store/apps/details?id=org.hostedgames.tinstar
Crusader Kings: Chronicles (by Paradox) - IF companion game to their strategy. Realistic medieval setting, very good writing.
