It's the best Heroes series in 3D. I loved the game so much. Every creature is now purely in 3D. Good rendering and animation. The campaign is quite the same as the previous ones in terms of quality. But it's a real treat to see creatures combat in 3D. The 3D is also still okay even with today's graphic quality standard. So it's worth the money, especially on discount.
The environment is great and meets the graphic standard of 2016. But the character model is so outdated. The control is terrible and not intuitive. The puzzle is difficult. And the UI is like Windows 98 style. One more thing, there's no exit hotkey or UI. So you have to manually terminate the program from Windows Task Manager.
