As a follower of khorne since second edition, I for one have been waiting for a codex like this. It doesn't quite hit like a ton of bricks like our 4th ed codex did, but I finally gives us a fluff army and we can still be competitive. GW is after all a model company first but with the next few releases coming up it shows that they might be listening to the consumer once again at some level.
I was on the fence about continuing to play 40k. Truth be told in the past 3 months I got very heavy into warmachine. Then this codex drops and I am once again reinvigorated with excitement that I have not felt in a long time. I'm painting my khorne army again and loving every minute of it..
I like this new codex and can not wait to see what GW has coming out soon as far as it goes for the other chaos gods
