I've been playing Heroes 3 for almost 10 years, and I've come to the conclusion that I'll never play as the Tower in important games. Why?
Let's start with the heroes. There are no decent warrior heroes at all. And that's a fact. There's simply no equivalent to Solmyr, Valeska, Crag Hack, or the others. What's offered is just subpar, as they all have random skills.
Among the mages, Solmyr is, of course, a masterpiece. But... he's just a mage. That is, if you lose the ability to use magic, you'll likely lose the battle 90% of the time.
So, in general, the Tower:
+ Solmyr, Syra (diplomacy from the start is a nice feature, although not for tournaments)
+ Lots of good magic in the guild (although sometimes only elementals appear:D)
- Very expensive (you need a ton of gems, not to mention the mages who want a little of everything)
- Not a single warrior hero. At all. As a result, by level 20, you get a hero with stats of 2-2-15-15 and no skills like defense/attack.
- Consequently, artifacts like the Cloak of Negation and the Orb of Disruption leave you defenseless. Because when Solmyr with 14-14-3-3 attacks you, you'll lose even with a stronger army, proven.
Regarding the creatures:
1) Gremlins. Upgraded Gremlins are the main force at the beginning of the game. By the middle of the second month, they are useless. Compared to centaurs or pikemen, they're just meat.
In general, in serious battles, they're just meat. "-"
2) Gargoyles. Meat. They have weak stats, lose to dwarves, archers, harpies, but they can fly. There's not much more to say, "±".
3) Golems. Lots of HP, decent defense, resistant to magic, but low speed. Good for defending the castle and as cover for titans/mages. In general, compared to similar creatures from other castles, "+".
4) Mages. A great unit. Good stats, no melee penalty, they reduce the cost of magic, and there's no penalty for obstacles.
Definitely, "+".
5) Djinns. In a word, garbage. 40 hit points for a level 5 melee unit and low defense is a joke. My gorgons are laughing quietly in the corner. They can fly and cast spells, which partially saves the situation.
"-", definitely. Their place is on the fourth level, but not the fifth.
6) Nagas. This is the Tower's main strength. They don't quite reach the stars in terms of stats, but their retaliatory strike, 110 HP, and 30 damage (!!!) more than compensate. The best level 6 unit, even a little stronger than the Death Knight.
"+", of course. Even two pluses:D
7) Titans. A very ambiguous unit. As giants, they're not bad; the cost is quite commensurate with the quality. But as titans, not so much. The undeniable pluses: 300 HP, 60 damage (!!). The minuses: very expensive, average attack/defense, low speed. For the same money, archangels look much more attractive... as do the creatures of the Citadel.
But I'm nitpicking, "+", albeit with a stretch.
In conclusion: an unreasonably expensive development, no good warrior heroes, a good mage hero (Solmyr), only two really good units (nagas and titans), and outright meat in half the slots (hello djinn, gargoyles, and gremlins)...
I've long since given up on this castle. There are too many variables that can simply ruin your game (like various orbs, cloaks, and a poor map).
Maybe I'm missing something, but I'd rather play as Castle/Dungeon/Swamp...
