Well i am playing it right now :-P since a prototype version is now available. At first sight it's really complex mining game, with an economic simulation of a division of labour, not only can you buy and sell ressources, goods, you can also lease out or fulfill contracts to do this work.
It reminds me a lot of The settlers (in case you remember the 90ies), which had a somewhat similar gameplay and graphics approach and maybe the Anno series, but never played this one.
Apart from gold mining, there's a lot of other work, like cutting timber and then making boards and beam out of it to eventually build some workshops etc.
As you can see on the screenshot, it's really crowded already with some 1200 test players and not much land left to prospect.
Certainly will need to understand the game mechanics a bit better (now i am just loosing money), and not sure how to actually mine gold etc.
All this might look a bit outdated, on the other hand, for blockchain purpose and all those gambling and micro game dapps, this one looks quite like a "real game"
