Forget about the storylines; the main thing is that they should be logical. After all, the plot is secondary; the gameplay and nuances are primary. For example, why does a castle, destroyed after an assault, immediately get restored? Wouldn't it be better to make this process gradual? And why spend so much effort on alternative upgrades when you could, for example, make repeated upgrades for certain types of units?! And why can everyone have exactly 7 units under their command? You can ask many such minor questions, which together create interest...
As for the plot, I hope that in the 6th part, it should become alternative, with the ability to influence events. That's what makes the game truly interesting!:cool:
