I am actually disgusted at the negative feedback this extremely helpful post got. I know it was years ago but it really helped me today.
The workaround was so easy so I'm so thankful that I found this very helpful post. I was honestly about to lose all motivation to continue playing if I hadn't come across this.
I'm amazed people are saying its cheating...no, it's simply a different way of playing. I don't think it's cheating, it doesn't take away any challenge, it simply takes away all of the tediousness!
I literally had no idea that the game was designed like that, I genuinely thought the point was to build one kingdom. So, when I completed the first ambition and read 'new game' on the next ones, my heart sank. I was invested in my kingdom and my heroes. I played through the first ambition as efficiently as possible, so I only made new heroes when I required their buildings to increase the aspect cap and I chose all the quests that earn the most RP so I could build all the buildings in as few quests as possible. Because of this, there's still so much more I can do! There are several heroes still at level 1, several more kingdom aspects to be earned, and lots more quests still to do!
I think it makes so much more sense to play like this and continue with the same kingdom. If you don't agree that's fine but don't be negative or mean to someone just trying to be helpful. I am continuing the game thanks to this person alone.
Thank you.
