What is your opinion about Heroes IV?

Auto-translated

Damn, so many of you jumped in at once! :D
And each one praises the fourth game and criticizes the fifth.:D

For example, I prefer it when heroes take the most direct part in battles, rather than standing modestly on the sidelines and casting spells and launching projectiles at the warriors fighting on the battlefield with impunity. It turns out that they are like members of parliament with immunity.

Of course, it's brilliant to expose a powerful mage to the danger of being killed in battle. It's much better to put him in front of the troops with a heavy flag in his hands. No, no... why put him far behind the army, where he can calmly cast spells or skillfully command it. Just because he's near the army in the fifth game doesn't mean he's 10 centimeters away from it.

artifacts are much more diverse

Really? I didn't notice.

In terms of skills, both have their advantages

Uh... what, half of the skills in the fifth game are useless?

All the 3D embellishments in the fifth game, although beautiful, unnecessarily clutter the space

Nothing is unnecessary; they are beautiful, and they create a wonderful picture. They don't clutter anything.

it's more interesting to take in large spaces and make plans for future moves, which is difficult in the fifth game due to all the fancy decorations that make it difficult to see useful items

Hmm... well, no offense... but that's nonsense. The "fancy decorations" don't bother anyone, only those who don't want to see anything else. Useful items are highlighted:p The camera rotation is a very convenient feature! And the fourth game doesn't have it... but it would be very useful, because there are a lot of large objects there.

A gaudy, cluttered map, completely unnecessary 3D

Even though graphics aren't the most important thing... the other parts can only dream of being like it:p
Considering the graphics is the last thing you should do.
