I'm a dwarf and I'm digging a hole...
Those of you who like the Yogscast will probably be aware that Simon (Honeydew) voices the Dwarf in the full game. It's quite fun, as a fan of the Yogscast, to be able to hear his Dwarven voice order you around and tell you how to be a good Dwarf. Those of you that don't know of the Yogscast can check them out here and I've even done a review of their ongoing Minecraft series Shadow of Israphel.
It's a simple point and click game where you control dwarves so they gain gold, gems and other items. There are also caves full of bad things such as lava (which burns through walls and can only be stopped by TNT) and water (which can be stopped by building a wall in its path). As well as the digging element, there is a fighting aspect. The Dwarves and Goblins fight each other and if Goblins aren't dealt with, they'll attack your base.
Get it, seriously.
Whether you're a casual gamer or someone who genuinely enjoys strategy games, I would suggest this game be added to your collection- I mean, it isn't as if you'll be paying for it and it's also a truly awesome game!
