This is a fun little strategy turn-based game where you compete with other dwarves to dig tunnels and the mechanic for digging the tunnels is interesting. It can lead to you creating a path from the monsters to your enemy's miners, beating his men down so they spend more time fighting and less time mining. I often find myself getting sucked in and lost in it as it's quite addictive and worth a buy if you are looking for a time wasting opportunity, but there's nothing really amazing to consider it a must buy, by any stretch of the imagination.
