Ran a recent demo of Warpath and KoW in Pullman earlier today. Had ~515 pts of each army, Undead vs Elves and Aun'Tai (golembane's Tau list) and Corporation.
Ran 3 games over the course of a very-slow 6 hours (They were all with people right at the end as a pathfinder society group showed up and was organizing). All three used the Warpath, and everyone chose the Corporation for some strange reason.
(For anyone interested, it was 3 sections of Veterans with the upgraded rifles and a Flamer, and a Commander, vs 2 sections of Locust warriors (Fire Warriors) with drones, 2 teams of Mantis warriors (Tau Pathfinders), and a Spirit Guide (Ethereal). The KoW setup was 2 regiments of Skeletons with Dogs/Rats, 2 regiments of Revenants, a Troop of Ghouls and a Troop/Half-regiment of Zombies, while the Elves had a regiment of bowmen, a regiment of spearmen, a troop of scouts, and two bolt throwers).
I think the Tau won in all the games (Their universal special rule needs to be +1 for shooting, but not melee or something. That or make them Elite. Either way their Att needs to drop.) This was probably in part due to forgetting the veteran's Elite and forgetting the entire first two games to give the -1 to hit if you moved and shot. The rest was due to stupidly good rolls on the part of the Tau, several of which I should have ignored in favor of attracting another game.
Luckily, despite only having three games I probably had close to a quarter of the people who came in the store over the course of the day express interest in the overall game, and the tagline of "It's like Warhammer, but balanced, cheaper, and so fast you can play with a chess clock" really helped entice those who were familiar with GW products.
Hopefully I'll be able to get more demos in at this shop, as the owner has expressed interest in stocking the products if enough customers seem to like it (I think the presence of a strong Pathfinder presence will really help since the models are so darn beautiful and detailed, and are perfect for a DM or discerning player who doesn't mind a few extra models).
Btw, if Nightsword is reading this, do you know if Mantic is still offering/will be offering that free army pack or whatever the promotional thing is if you manage to get your FLGS to stock Mantic stuff?
