2. Now the differences.
It is indeed a RPG.
2.1. You've got only ONE hero.
2.2. Your primary objective is to run about the map and do some "Quests". Search and destroy that bunch of bad guys, find these artifacts, help this guy to find his lost stuff and that guy to find a good wife. All kind of those stupid things a good "Knight" should do for living. That is for Money and Experience.
Some people like it and some do not and even find it stupid and boring.
The "strategy" component in KB is here only as long as there are many packs of monsters walking around the map, and all these monsters somehow do not let you pass through. Or own the stuff you need to get. So the solution. Hire a good army and smash them out.
2.3. That means that in fact there are no such thing as "Enemy Hero(s)". Formally, Enemy Heros are here, a lot of them, but they are completely static. It's better to say that there are "heroless" packs of monsters and "herowith" packs of monsters. In the BATTLE these heroes act like in HoMMV, cast spells etc. But they do not move around the map, do not hire units, do not upgrade their level. They're really just a part of monsterpacks, not real heros.
2.4. Castles.
Yes, you DO hire your units in the castles.
However, you do not OWN any. You do not build or upgrade anything there. Castles are something like 'Tavern' where you can hire some types of units. Artefacts and spells in limited amounts are also on sale there. When you fulfill quests, new Castles with new types of units become available. Sometimes these Quests are about to please Castle's owner, sometimes to kill or conquire him somehow.
2.5. Money ! VERY different from HoMMV.
No castles means no fixed income!
You earn your money very hard way, especially in the beginning. As trophies in the battles. As payment for Quest fulfillment. Money is really an issue in KB, and there are NO easy ways to earn it, like pressing "next" button in HoMMV.
I think that a person without good Battle Tactics skills would not cope with this issue. You see, bad tactics imply big unit losses. And your unit losses should be covered by battle's "reward money" (trophies) If your losses cost more than that trophey's money, you go bankrupt very soon.
A pecular thing is that "reward money" do NOT depend on ABSOLUTE strength of your Enemy, but on his RELATIVE strength to YOU at the moment of the battle!
Absolutely NOT LOGICAL , but forces anyone to consider his unit losses and his Battle Tactics skills very seriously.
If you attack a weak enemy you may suffer no losses, but get little money. If you attack a strong enemy, you get more money, but also suffer unit losses you have to pay for. You're well off only if your trophies are bigger than your unit losses. A thing called "Game Balance" by some.
Although you can get some pocket money by doing more of those stupid side Quests, (There are only several main storyline Quests and a LOT of side Quests) its a good Battle Tactics skills that really helps.

All right. I would pause here. Would gladly answer any questions.
