What is your opinion about Heroes IV?

Here, I disagree. I wouldn't say that modern, beautiful graphics are extremely important, but... it's not inherently bad either. I had extensive discussions with those who worked on the fifth installment of the "Heroes" series, which had quite modern graphics at the time. And their main problem wasn't the 3D graphics at all, but rather the "legacy of the third game" (they surpassed it, but the problem is that the third game itself was a black mark in the series for me until the release of the sixth game). The problems don't start when developers make the game's graphics modern. The problems start if it becomes the main priority in development. That's why what's inside the game is most important to me. That's why I enjoy playing both the "modern" fifth installment of the "Civilization" series and the 2D "Eador," which doesn't even have animations, let alone 3D.
