Hi, I'm Shoggy, a weird guy that runs minimal-turncount World Conquest speedruns of Total Warhammer (the technical term is Blitzes I've been informed), and then writes them up in detailed After Action Reports. It's been repeatedly suggested that I actually post these here on the official forums, so here I am.
These runs are just about the epitome of cheesiness, generally relying on at least one near-game-breaking campaign exploit per run backed up by some of the most manipulative battle gameplay imaginable. I do my best to explain all the silliness invloved, but feel free to ask if you want clarification (or are interested in trying something similar yourself!)
The current standing record for VH/VH and below, set just this patch, is 34 turns with Vampire CountsWrite-up: Nagash was SLOWGIF:
(and for those interested, the current Legendary record is 99 Turns with High Elves, set by /u/Beartew)
