If the map was generated and immediately launched in-game (as is always done), then using the seed, one can find out the artifacts in Dragon Utopia and other things determined upon launching the map. This requires certain reverse-engineering skills (more substantial than simply using ArtMoney), but this task cannot be called very complex.

If it's possible to restore what was present during the initial generation via the seed, then there are no questions. That is exactly how it was. Although until today, I thought—as did Wicc—that only the map could be recreated, but not its contents. Even if you recreate the map, it might be possible to achieve the same generation through brute force, but that is too tedious.

In general, no one doubted that with a certain level of knowledge, there's no problem cracking a game like Heroes, where everything is located on your own computer.

The seed can be removed from the map description; then restoring it via an open section of the map would be almost impossible, and neither the client nor third parties would be able to find it. But the host generating the map can still find out the seed (if we assume they know how to restore a map from a seed, then this is not a problem for them).

If a person possesses such knowledge that they are capable of restoring a map via a seed and has the desire to know the layout, it would be easier for them to crack save passwords, which in my opinion is a simpler task. Not to mention that a dishonest player can always open a stream and find out everything from there.

In any case, I don't see any global problem. 99% of players do not possess the knowledge required to break protections while simultaneously possessing the desire and skill to crush others in Heroes.
