Where did people learn to play Heroes?

I remember back in the day (I was in the third grade), I didn't have a computer at home, so I played at my parents' workplace. There was an old computer there with an old 80286 processor, and I think some of you might remember it. There was a game called King's Bounty on it. I got really hooked on it and played it all day long. Then, a few years later, I saw the first Heroes game at an internet cafe. It looked kind of similar to King's Bounty, but it wasn't quite the same. At that time, I didn't really appreciate it, and I didn't even remember the name. And then, around the year 2000, when I finally had a computer at home, someone recommended that I get the third Heroes game. So I bought the disc and played it, and it was pretty good. Then I gradually got into it and started to enjoy it, and then I played the fourth and fifth games.
