Ancient-Red-Dragon: You are supposed to read the manual before playing the game, which explains points like monsters from different towns being on the same team causing your troops' morale to go down.
Yeah I guess I am not so much into reading game manuals, at least nowadays. I prefer if the game itself teaches me to play itself (e.g. RTS games like Starcraft did that brilliantly, by introducing new kinds of buildings, units and tactics to the game as the game progressed; no separate tutorial needed either).
I actually knew that "monsters from different towns lower the morale" from the HOMM FAQ I read... but then it felt as an unnecessary complication to the game. If I was wandering around with one of my heroes and it was running out of troops, I went to one of my castles to get reinforcements... but how the heck do I remember if those units in that particular castle are the right type of units to add to that hero's troops? Why should it even matter? Am I supposed to wander back to the "right" kind of castle to replenish the troops?
It sounds just as odd as if in e.g. Starcraft there would have been some severe penalty if I group together tanks and ghost units. Why should it matter that they are "different" kind of units? Does it somehow make the gameplay more interesting?
Also there sure was a wealth of different kinds of units... but that also felt a bit unnecessary. Ok so there are those fairies and gnomes and trolls I can produce... it is not apparent why they exist why should I e.g. produce fairies instead of gnomes or trolls? Again I take Starcraft as an example: most units have a pretty clear reason to exist in the game, they are used for different gameplay styles. Easier to tell why there is a tank or medic or a Valkyrie air unit in Starcraft, than why there is a troll or fairy or gnome or a big snake-kind of creature in the game. I guess they all serve some kind of purpose, but it is not quite apparent what it is. Fairies move faster but are more fragile and cause less damage, right?
Maybe all that becomes clear if I just keep playing the game (longer than merely just finishing the first campaign mission), but until then...
Ancient-Red-Dragon: As for "defending," in games like HOMM 3, defending doesn't work very well and a defense-based strategy is a surefire way to lose the game.
I didn't mean I was doing nothing but defending, or even concentrating in it. Actually it was quite the opposite: I had three or four heroes wandering around with their troops, and I had just transferred many units from one castle to one of the heroes.
Just as the hero had left to a distance, the enemy attacked that castle of mine when I had only few troops inside. So I easily lost the castle because none of my wandering heroes could reach it in time to help defend it.
Then again I guess the point of the game is not care that much if you lose some castle etc., just build or conquer another one...
Matewis: Apart from defending not working like you said, i.e. you
have to constantly explore and expand (not feverishly necessarily, unless it's Shadow of Death), there's one other perhaps even more important thing that bears mentioning for anyone struggling with the game: Don't have your main army waste time running back to towns to gather troops! Have dedicated 'ferrying' heroes do that for you.
Yeah maybe that is one thing, as I wondered am I supposed to run back and forth to the "right" kind of castle, just so that I don't cause any lower morale by mixing fairies, trolls, gnomes and snakes into the same team...
Maybe that is a good approach then, using other heroes mostly as mere delivery guys.
Also, that is one important(?) thing that the FAQ mentioned: you shouldn't necessarily try to improve all or even most your heroes, but try to improve one of your heroes mostly, even though you have several heroes/parties. I guess things like that become clear only through playing the game a long time, at first I had no idea whatsoever whether I should have only one or as many as possible heroes/parties (different kind of heroes I guess, like some are spellcasters, others are fighter heros etc.), and whether I should try to improve all of them evenly or not.
