Looks interesting. Is it anything like:
1) Mortal Online:

2) Xsyon (formerly Xyson):

3) The Repopulation:
www.therepopulation.com
4) Wurm Online:

There're a number of others. These types, including the above, don't have huge populations.
It must be alike because it's Sandbox MMO, but how does it differ from those above? Even games in similar genre have differences. I've only played Wurm Online, so it's hard for me to measure. I will add it's hard to play more than one of these games if you want to really get into it.
Looks fun. i added to my favorites.
Here's another on the horizon:
