DISP rules we have to follow at work....moving onto a new project, which relates to some of them.
Tried reading them. More than once I've tried.
That pretty much sums it up.
But hey, if complexity and minutiae float your boat, go for it.
Me, I'll stick with the rules I know (40k does have a convoluted rules set, but I've pretty grown up with them, so it's been incremental).
