Played a single game of 40+ minutes and finally managed to eradicate the Gothi; it was really satisfying and felt well-balanced to me (until I got the upperhand in Tech level). Good job on your game!
Is there a win condition, or some kind of dialogue when you beat the AI though? Nothing appeared when I conquered the last island on the map, and I cannot expand my field of view further.
Thanks for the comment!
In each game there are 2 enemy tribes, so it looks like in your case one of them has been spawned on an unreachable cluster of islands, sorry. I considered such situation too unlikely to check for it, but it seems I was wrong.
Yes, there is a win condition: both your opponents have to lose all their islands (you don't need to colonize every island). You will be shown a clumsy "Victory" popup :)
