The Kremlin is being created together with the CoreWoG team and, in theory, should be released in WoG 3.59 in the future (which has more plans, but is not expected to be released anytime soon). Our HotA add-on, however, is an add-on for the original Heroes (SoD), and essentially has no relation to WoG. We have completely different goals (balance, multiplayer, the classic nature of our innovations) than WoG (a variety of options, innovations, sometimes even imbalance). The only thing is that HotA can be installed on WoG as well, just like on the original game. We also use some of WoG's features to implement our ideas, including the ERM language for now. And, of course, we maintain full compatibility with WoG 3.58f. Initially, our project aimed to unite all the actually working teams creating new cities (at that time, there were about three of them, not counting the veteran cities of Bastion, Haven, and the Kremlin) and create a truly large-scale add-on, as people were already tired of waiting for 3.59 (at that time, it was a kind of "myth" - now it is being developed, albeit quite secretly, but then 3.59 was not taken very seriously). Of course, later much has changed, as has the overall situation in modding for Heroes 3, and our goals have also changed. But the main idea remains the same: to create the highest quality, classic add-on for Heroes in the shortest possible time (while we try to maintain an open dialogue with the community, accept any ideas, and the project is, in essence, much more open than all the others).
