Probably the Limited Edition, as it has just the right amount of lore fuel like I love (Arms and Armament, anyone?) without [i]quite[/i] crossing into triple-digit "Why did I buy this MJOLNIR cat helmet?" territory. However, I cannot guarantee that I will not do something stupid which I'll regret and actually say the words "Ghost Edition" when I'm standing at the Gamestop cash register tomorrow, so all bets are off.
