While I understand that it's just part of Hex Empires, I do dislike the mechanic where destroying the Capital completely destroys the enemy.
I would have preferred there to be a way for them to reclaim it with troops from surrounding cities, but oh well.
It is quite good, but soon becomes "Pay to win".
There is a 30 minute wait for one quest that I am currently on.
The only way to speed this up other than by 5 minutes, is to buy an item using real money.
