The lack of temptation to optimize the playthrough – I consider this a blessing. I completed it and immediately submitted it, as I don't have time for optimization.
This temptation is one of the most alluring of all Heroes temptations – it's no joke; sometimes it even prevents you from sleeping soundly. Although, tearing your hair out in frustration because of the impossibility of an improvement that has only now become obvious also doesn't contribute to good health! :)
