Actually, I think Frontiers (<a href="http:&#x2F;&#x2F;explore-frontiers.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;explore-frontiers.com&#x2F;</a>) might be even more ambitious Unity-using game, but the developer working on it is in over his head. Still, what he&#x27;s done so far is amazing already.
