Think Minecraft/RTS mixed together.
They have a kickstarter going now, totally blew it out of the water. Got this video from them showing how the alpha is coming along, there are a few others out there as well.
Given how many people here like Minecraft, figured this might be right up your alley too.

This project so far is the only Kickstarter project I've contributed too, it's pretty sweet looking.
