This is actually one of the problems. There are indeed quite strong players, even on the original game, those same "founding fathers" of Heroes, but they won't come to play with us, not because they dislike TE, they can only "justify" their unwillingness to play with this mod, but because they are worried about their status. How can I be a "founding father" here, but be a mediocre newbie there? This is most likely a psychological issue. After all, we all know that TE is still the same Heroes, the heroes don't run around backwards, orcs don't cast "Armageddon," and the other races don't cast "Wrath of the Horde." TE doesn't fundamentally affect the game mechanics; TE is primarily about striving for maximum game balance. This is what needs to be explained to everyone who wants to improve their gaming skills, rather than playing "Old Friends" for the hundredth time on the original Heroes of Might and Magic.
P.S. By the way, me and Player-76 have played "Underground Treasures" on Heroes of Might and Magic countless times, about 3-4 years ago.
