What is your opinion about Heroes IV?

Wasn't it tedious to figure things out in the fifth game? :) ... the hero upgrade system is even more complex... so upgrading a hero is actually a huge plus for the fourth game...

No, it's just that in the fifth game, a skill tree appeared right away, and it was easy for me to figure out the upgrade system... Besides, when the fourth game came out, I was still young and very inexperienced:D :D. I didn't feel like thinking...;)
