Respect to the author of the thread; this is a very important topic because many people want to play the second game (nostalgia + it's still a great game), but when they start playing, they realize that many things are different compared to the third game, and they have forgotten what and how things work over the years. Since there wasn't a similar guide before, and it's too much effort to learn everything from scratch, they sadly return to the third game. I remember struggling with the second game when I started playing with Loveless. First, I found out that there's no "wait" function in the second game :o, and then I wondered why the vampires weren't regenerating by biting a large stack of creatures without killing anyone, and many other things. Deep Mike lost his first game and played several more because he didn't know that you could simply block a teleport with a single unit. He almost lost to Leos because he didn't know that, after entering a teleport, you can't exit by pressing the spacebar like in the third game; you have to move back and forth (and there was a pack of phoenixes on the other side; it was a Hotspot map, the second one). Now, a player who wants to relive their youth and enjoy this excellent game doesn't have to learn through trial and error or by asking other players; they can read this guide and be well-prepared for battle...
By the way, I remembered something about the spacebar, and it's not mentioned in the article; it should be added:
In the second Heroes game, you can't, like in the third, visit an object or enter/exit a teleport without moving away from the object and back to it; therefore, visiting an object or teleport multiple times in one game day is limited by the length of the hero's turn. In the third game, you don't need to make any moves for this purpose; you just need to press the spacebar and visit the object or enter/exit the teleport an unlimited number of times in one game day.
