The minecraft vibes can put many people off or keep them from taking it seriously, but this game packs a punch and requires a lot of planning. It's a perfect hybrid between tower defense and resource management. A lot of content has been added that forces you to keep grinding to unlock the next best thing. Build your fortress, and defend it.

I began playing this game when there were only bows & arrows and 2 or 3 different ores to be mined. Now there are several mineable resources, all at different depths. You manage your people making sure you have enough archers to defend you, workers to reduce the amount of work you do personally, all while making sure you have enough farmers to feed everyone. Easily worth the money, especially with the multiplayer mechanics coming in the future.
