I once ran into a computer implementation of an old board game that seemed rather interesting, unfortunately I am unable to recall either. What I do remember:
Probable
- Java (advertised support for linux)
- hex tiles
- recruit squads of magical beasts for combat
Possible
- recent IOS (or Android) version, unrelated to the Java version
- hex tiles arranged in concentric "terrain" zones, the goal being to reach the center
- special (angelic/guardian) creatures with greater powers
- two modes, one for recruiting and one for combat
