An Retrospective on How We Got to Be In This Place In 40k Gaming

Hello again readers today I'm going to take you on a journey through the gross gelatinous nimbus that is the 40k "meta." What is Metagaming? Well Wiki tells me that:
"Metagaming is a broad term usually used to define any strategy, action or method used in a game which transcends a prescribed ruleset, uses external factors to affect the game, or goes beyond the supposed limits or environment set by the game. Another definition refers to the game universe outside of the game itself. In simple terms, it is the use of out-of-game information or resources to affect one's in-game decisions." -Wikipedia
Thanks Wikipedia! So Metagaming, Meta or more specifically 40k Meta refers to the climate of the gaming troposphere in essence what the people playing the game are doing to effect the way the game is played. And in this day and age of Psyphilemen Dreads (I had this term and it's face) Razorback spammalam and every unit having meltaguns the "climate" of the 40k meta is Mech.
