Think the main take away is the lower rated scenarios always suffer from playing to a time constraint and not being allowed to finish naturally.
Especially for Seize the prize, if your unlucky enough not to get and dig up the prize first turn you can concentrate on wiping the opponents army as it won’t end till your both on 25%.
Unless someone has a model with fly then it’s just miserable
The problem is that “this scenario is fine so long as you have three hours to play it” isn’t really a fix. Tournaments tend to give quite a lot of time, so scenarios should be able to be played out in that time. A scenario that is only fun if you get way more time than the other scenarios is not good.
