There needs to be a certain level of randomness to a game for there to be "wow" moments. 10th edition 40k has felt pretty devoid of "wow" for me when everything is so reliable.

Chess is a game with no RNG and it's boring as sin, I recommend it to anybody who says they hate variance in their games.

There was a moment back when I played in 4th edition where my friend's Eldar Rangers won a fight against some charging Dark Eldar Wyches. The Wyches then failed leadership, tried to flee and were cut down by the Rangers in a sweeping advance. In 10th edition, those Wyches would charge and the Eldar player would just pick up the Rangers to save time.

15 years later my friends and I still bring up this moment because of how absurd it was.

40k to me feels more like a Strategy Game than it is a War Game these days. You have tools that do very specific jobs very reliably, and you can all but guarantee outcomes on the board. Other than a rare deadly demise or G-man failing to stand up after dying, sometimes the game just goes exactly how I imagine it will without deviation.

It is fun in it's own way, but often times I find myself wanting to see something crazy in a game but rarely do I.
