For those of you who always liked the idea of Dwarf Fortress, but couldn't get on with the UI or the increasing genocidal nature of the gameplay, there's an interesting Isometric game out called 'Gnomoria' that pretty much is identical to the basic gameplay but without as much 'Fun' going on.
The Good : Nice interface, no more trying to remember 3-4 keystroke combinations to access certain menus. Good graphics engine with objects changing colour depending on what rock they are built of and moderately easy scrolling along the Y-Axis.
The Bad : Doesn't come across as 'deep' as DF, you cannot pick where you embark or what you embark with (though it's far, far harder to die at the start), it's around $6, which whilst cheap, DF is Freeware. The Music is 8-Bit Midi style, and I find it pretty grating.
The game is still in Alpha at the moment, and is available on Desura, so the gameplay will be expanded on as time passes, and so far is looking pretty promising.
