This edition of 40k is a lot more crazier in standard games then any before it. Lords Of War, Formations even Forgeworld units and lists are becoming common place in standard 40k, which can lead to some unbalanced games. Because of this most tournaments are being forced to put in place restrictions to keep tournaments balanced and enjoyable for all attendees. Unbound of course is always banned, even at GW's own Throne Of Skulls.
But the challenge is finding the right level of restrictions, as players can be put off by restrictions as much as the idea of fighting an Eldar Titan or 1000pt C'tan.
So what restrictions have the non-gw tournaments you've attended had in place and what did you think of them?
