In the second Heroes game, the Captain allows you to use the magic guild even when a hero is not present.
There is no city tower management in the second Heroes game (it exists in the third).

And are Warlocks good, evil, or neutral, like Barbarians????????

Unlike the third installment, in Heroes 2, the division into "Good and Evil" is purely conventional.
Usually, the "Good" side includes sorceresses (mages, the Phoenix Castle, and elves), knights, and wizards (the Titan Castle).
The "Evil" side includes necromancers, warlocks (the Black Dragon Castle), and barbarians.

It would also be interesting to hear opinions about the archer's skills and about the Shield magic, which protects against arrows (how effective it is).
And regarding the division into good and evil - it's not arbitrary, because this is evident when playing through the campaign, and if you look more closely, good and evil have their own opposites:
Knight (good) <---> Barbarian (evil)
Fairy (good) <---> Necromancer (evil)
Wizard (good) <---> Warlock (evil)

Oh yes, and regarding Heroes, I usually take heroes corresponding to the castle, but in general, I prefer Knights and Wizards. I’m not very familiar with the intricacies of Heroes II, so this choice is simply based on my preferences. :)
