Cannons are very all-or-nothing. In this case they definitely fell into the "all" category. They were pretty outrageous, and definitely dictated the game. To be honest nearly all of the luck was on my side. About the only things that went wrong for me were a couple of charge and pursuit rolls.
The Halberdiers did do important work, but even they were lucky. They tested for terror on their base leadership, and they also passed a steadfast break test on the same. I can't claim to have played the game brilliantly, but my troops fought well.
Kislev is still on the cards, but getting all the pieces into place and actually making it happen may prove more difficult than it would have before AoS. Also, I need to assess whether the game will need any major change-ups in order to make it more interesting and less of a static grind. These big games choke the table up with troops something shocking. Might be good to find a way to change that up a bit.
Kings of War is very different, but I think it's a pretty good game in its own right. I think people hoping it will be a straight-up replacement for Warhammer will be the most disappointed. It's not quite like-for-like, although it's closer than Warhammer and AoS.
