From the couple of games I played with Vitalik, I realized that he's a great family man, which is awesome!
By the way, his son took the save files from the first game with his computer, and he doesn't remember the password. To be honest, I destroyed two of his castles, so I don't think it's worth finishing that game.
You play really well, it's a shame you don't have much time to play in this tournament...
