This is the essence of old-school gamers as it is.

No, not entirely. I've tried playing the fifth installment many times. Yes, I could play it. But it's very boring and uninteresting. The game doesn't grab you, while the third game has something special that captivated a huge number of people at the time. I still play "Heroes 3" from time to time because it's a truly turn-based strategy at the highest level. If any other similar game could compare to it, it would be "WarCraft 3," but that's already a different genre of strategy, so the comparison is inappropriate.
So, don't put labels on me; I just don't like the fifth installment in the series. But the sixth one gives some small hope...
