"Two Seasons: Winter - Spring 2017-18". Online games.

On the third attempt, I broke through to his main base, took the blue main, and cleared it out, also getting a Utopian (level 5 artifact). My opponent didn't want to give up, he just kept running around. I chased him into the third dungeon, but there was no air, so I had to search for him. I found another Utopian there, and while he was turning around and running back, he entered my dungeon. I caught up to him and defeated him. Thanks.
