Ooooh! Oooh! My turn!
Name's Scott, but I'd answer faster to Xabre anyway, so let's stay there, shall we?
I started mini gaming a few years ago with a crudely constructed Mordheim league built by some friends of mine. Shadow Elves were the order of the day, and their shooty death brought me my fame and glory until a friend of mine learned what a mounted knight and a bunch of squires could accomplish.
From there I swore I'd never get involved in one of those large scales miniature games... and was promptly beaten over the head by the idea of how cool the Dark Angels could be.
I lost every game with the angels and their Plasma Cannons. After the crushing defeat of my Deathwing to a bunch of gaunts (you never saw so many 1s...) I retired the army, switching to Necrons.
Over a year I assembled a serious Necron Force, and never lost with them. I dabbled in Grey Knights for a while, and put together a beautiful (imho) Grey Knight Battlefleet Gothic force, with Forgeworld strike cruisers and my own custome built Inquisition Black Ship.
Now I've sold my Necrons and have moved onto Chaos, simply because I'd rather lose with an army with flavor, that I can enjoy converting and painting with....
Granted, I haven't played 40k in months... I spend most of my time nowadays on WoW.
