Yesterday I participated in a 40K Charity tournament. I'd only gotten to play 2 games of 40K this year so far, so I was rusty on the rules. It was 2000 points and did not use the standard missions from the book or anything. The organizer created random missions that we all played.
There were no prizes for winners. Everyone received a door-prize, and everyone received a 'completion' prize if you remained for the entire tournament. I think there was an award given for the best-painted army, and the organizer also had every person roll 20d6 and whoever rolled the most 1's got a prize. All in all, there were 12 slots (and they filled up very fast ahead of time), so that was like 26+ prizes from my recollection. A lot of it was stuff donated by another non-GW manufacturer, along with some store-credit vouchers.
Nice tables, nice terrain, and great fun. We were encouraged to bring 'fluffy' lists, and I think most people did. This was advertised as a NON 'competitive' tournament (as evidenced by the lack of prizes for 1st, 2nd, 3rd), though a few guys still came with the obvious killer-instinct and it showed.
I played an all-Harlequin list and had a ton of fun with it. I went 2-1, but very few people played the games a full 4 or more turns. My one loss was a brutal beat-down, and two more turns would likely have seen me tabled. My other two games were heavily in my favor when we stopped. The scenarios were pretty wacky. :)
There were 4x Ork players, 3x Tyranid players, a Blood Angels player, a Dark Angels player, a Night Lords player, a Necron player, and me.
All in all a good time, but after a 10-12 hour tournament, I am pretty 40K'd out for awhile, I think. My current real love is Infinity, and I've got lots of projects for that in the works. But I do enjoy 'fun' tournaments for charity. Good good stuff. :)
