I didn't go, but my friend brought back some nice stuff.
He got me the stingers which I was real hyped for. Got the Spell Martyrs also which are real stylin. I was really surprised by the new character jack conversion kits. Torch looks pretty boss.
He also said he saw the Firestorm Armada models and told me that they are a lot bigger than what you think they would look be and looked really nice in person. I was thinking of grabbing a fleet but didnt really want to spend $60 on models that I thought were BFG scale.
He also brought back some flyers for some games coming out that looked interesting. He said he did a game of Malifaux and it looked really good. On top of that he said it was pretty economical compared to other games.
All together, even though I didn't go, Gencon gave me a lot of renewed hype for my legion and khador, which have been collapsing like the Roman Empire.
