Since the discussion about the past tournament is ongoing, I'll share my thoughts as well.
I tried playing this map a bit.
I replayed it several times during the first week.
The most interesting strategy, in my opinion, is to break through on the fourth day with gargoyles, archers, and fairies. Although I also broke through on the third day, the losses were much greater.
I built Phoenixes on the second week without using the market, so by the end, I had 10 of them. I captured the Titan Castle on day 137 and immediately built Giants there. I didn't play any further, as I saw that on the first day of the fourth week, I would be building a Dimension Door.
Personally, I think the most interesting strategy is to capture the Necropolis Castle and get a Berserker...
And the strongest strategy on this map was demonstrated by one of the best players in Heroes of Might and Magic II (at least in the CIS region) - a direct march to the Knight Castle, capturing it, and then sailing to the Titans, where he built Giants on day 127.
I could have built something on the second day, but I preferred the Shipyard, as it was easier to play with the collected artifacts. And I didn't see much point in building anything else - there were more native creatures! The goal of the battles was simply to gain experience for the main hero and collect artifacts. The tournament is an arena tournament, and as a result, the first task for the hero is to complete all the experience-boosting locations within the allotted time. I also liked the Berserker, but I couldn't get it - there was too much running around the map.
If there were standard victory conditions, it would be a different story!!!
