Many people are drawn to Warhammer for it's deep and rich back story, the endless tales of war between the Space Marines and whichever poor schmuck is in their way this week. But that's not for me, I really care little for whether the Emperor will ever return to life, or the ramifications of the Heresey, I also have very little time for Eldar stories. I do however prefer the more leftfield fluff that is perhaps more lighthearted in it's approach.
Maybe because I just find the stony faced serious nature of everything a case of the fun being sucked out of the game and every internet discussion being either a) GW are a bunch of money hungry wasters or b) how best to break the game so you never lose a game in your life ever. For me, my working life is all the serious I will ever need.
Even the Eldar, which I am so fond of, aren't safe. The most background I have ever read on the race (no thanks in part to GW's lack of material) has come from other sites. My views of Eldrad, for example, are based on light hearted conjecture. As an aside, on one GW coach journey, we had a quiz, and one of the questions was "How did the Horus Heresy end?". I'm pretty sure that everyone under the Warhammer sun knows that little ditty off by heart, so I rewrote it so that Eldrad won and ushered in the new Eldar empire.
I remember when I painted my Cutie Markers for Tale of Many Gamers, there seemed to be many who were reaching for the Exterminatus button because it wasn't in fitting with the universe that was created for them. They'll probably be even more annoyed when I add another three for use in Maelstrom missions. The funny thing is, that no-one seemed to mind when I converted a larger Command Barge for Zhandrek and called it the Pimp Barge, but thanks to 7th Edition, it will never see the field of battle.
That's not to say that I shun the serious aspect of the universe completely, it was only through listening to the audio books of Prospero Burns and A Thousand Sons that I developed an admiration for the character of Ahriman, I bought Shadowsun because of the novella and I have all 6 of the Eldar Path series which has also shaped my Eldar forces. I just wish that some people would embrace the less serious side of the community more often, lets have a discussion instead on who would win in a game of hide and seek, the Raven Guard or the Reasonable Marines, how much of a dick Eldrad is or those stupid sexy Xenos. Maybe it will creep into your gaming and that win at all costs attitude will make way for writing a list 'because it may be fun'.
