We’ve had this discussion before, whilst I can see where the comparisons are with Timber and Stone, there are substantial differences.
For one thing Timber and Stone is a lot more micro than Stonehearth is aiming for.
@SteveAdamo is one of the head honcho’s over there so he’ll be able to inform you more than I can.
Edit:
Taken from the Reddit AMA:
Q: What do you see as your competitors? Minecraft? Cube World? Castle Story? Timber and Stone?
A: I don’t think in terms of competitors, because this is a brand new genre and there’s room for multiple games.
First, even though we use voxels, we don’t play like Minecraft or Cube World at all. Castle Story, Timber and Stone, Towns, and Gnomoria are all better comparisons.
But all these games have their own spin on the “city management with building and crafting” genre that’s developed, which is great! For Stonehearth, we’re 100% focused on building the kind of game that we want to play.
