Titans are ultimately better because they are more durable.
And everything is bought because there are no resources for anything else on a difficult map (I was considering exactly this scenario). And if the map turns out to be more or less favorable, everything is bought except for Rakshasa and Golems; they are saved for other weeks.

There is always plenty of money on the map; I already wrote above where to get it. And without starting meat, you won't get this money.

Not almost, but always.

They attack when the danger is high. As a result, their entire army, which is twice as large, is defeated under the castle.

I just played against the computer (one elf) on a hero. I thought I would write something about it, so the second week turned out to be the Union week, thanks to which, on a medium-sized map, I defeated him on the 3rd week.

In the first week, I got ore, wood, crystals, and gems (I didn't touch sulfur because I wasn't going for mages, and the guard was inconvenient). Starting hero - Nur, starting artifact - a bag of gold. In the first-second week, I captured the Golden Horseshoe, the Lion's Collar, the Dragon's Tooth Crown, the Dragon's Flame Tongue, the Dragon's Greaves, the Flesh Tunic, the Emerald Slippers (sold), the Clover (sold), the Flame Rune (sold), the Sword of Power (sold). The second was Or, the third was Erling, then there was a Dungeon on the map, and there was Ingvar. Of the useful spells - Arrow, Regeneration.
I went for Summoning and quickly leveled up the Fire Warriors. If I summoned more than 30 Fire Warriors in battle, the opponent preferred to run away immediately)).
I got lucky with the week, but the computer would have lost anyway.
