Gameplay-altering features that can only be used against the same HD version, features that make the game incompatible with the original (i.e., bug fixes, corrupted saves, a timer that starts after "OK," a replayable battle) will be separated into a gameplay mod – a plugin for HD with some grandiose name like "HoMM3: Perfection" or "HoMM3: The Perfect Game" or "HoMM3: The Perfect Tournament" with a minimal number of in-game options, and I will distribute it with HD. It will only be possible to connect with the same mod, so there will be no confusion about which game and which rules we will be playing.
With this new HD, it will no longer be possible to play a pure SoD with corrupted saves, and frankly, good riddance! I'm tired of: "I want this feature, I don't want that feature, and this one is just garbage." That's it! Interface and convenience in one direction. Gameplay in the other.
Thus, the idea of widespread use of replayable quick saves in SoD online can be considered officially buried. Congratulations to all interested parties.
