Hey i've been following this game for a few days now and just bought my first country of Vanuatu! It's now worth 2.7ETH if you want to buy it!!
Exactly as you said if you wish to buy it. But what for? There are plenty game with block chain asset. This one dont looks like one.
In games with block chain asset price is determinated from most recent sales, not by offers that owners of that asset put them on sale.
