Great work @SuperSnark!
This one is definitive my favorite It's really clean and simple, yet catches the essence of LaS. For my taste the complex one is a bit to cluttered/full. Can you try to increase the letter spacing a bit in order to make the logo a bit wider?
I see this one as a good candidate for a module icon Can you probably save some space when just using LaS instead of the full title? Maybe the figure needs to be simplified a bit as well if we want to bake it into a - let's say - 32x32 pixel icon.
I think it's probably best to keep this on the simpler side. I think I was trying to incorporate too many concepts at once - the "shadow" element, the chess element, block towers, etc. But a logo doesn't really need to embody it's components so much as present a correct general "feel". I think the Wicked Queen font is strong enough graphically on it's own - and then we present it in the L&S color palate of red/black/white and the banner represents the conquest-based gameplay.
