Dark Eldar <3 Commorragh called for me... Maybe it is the cat inside me who got overwhelmed by Skavenblight and she didn't want to keep up with Night Runners anymore. Now she can have all the slaves and raiding in the world... The aesthetic of the army is definitely my favourite out of them all (...partly because I got here after 2010... Kruellagh the who?). I wouldn't say no to a shrine of aspect warriors though... or that one ork who left me some room in the trukk...
Probably Chaos. I mean seriously, there is an allure to destruction and annihilation, I could learn to live with a tentacle or horns, just let me blow stuff up. Then again, this also sounds very orky... Chaos Orks anyone?
In that case you should go with the Necrons, since they technically have more advanced technology than the Eldar. Orks iz too chaotic fer Chaos. We'z too much for Slaasesh, too fast fer Zeach's planz, get more skullz den Corn can stack an' iz too big ta be sick. Dat silly Nurple'll neva get me.
NEWB! My flavor of the month: Skitarii. No, not the whole Adeptus Mechanicus,but Skitarii. They look cool, they combine aspects of other factions that I deeply enjoy, and their fluff is fun. My high school sweetheart: Catachan Guard. I used to be the sort of guy to walk buy a bunch of nerds and go "Seriously, what's so cool about this miniatures collecting thing?" I made fun of some dudes playing it once, they told me not to knock it before I try it... I tried it and got hook. My first army was CG. They resembled Vietnam Army/Marines. I had to have them as I was in the Army at the time. Keep Going Back: Tau, Necron, Space Wolves. These three armies happen to be the triangle of love of sorts. I sell, trade and buy these armies on a somewhat rotational basis. You'd think I'd just collect all three and rotate like that... Well, you're right I should! First, to collect my flavor of the month. What I'll be playing in EC: Eldar. I like elite style units that have a specific focus and have to rely on finesse in order to achieve their goals. Plus, I hear it'll likely be the least populated faction, which is what I usually strive for on any game I play.
Space Marines, we got a thread for why: http://forum.eternalcrusade.com/threads/they-are-my-space-marines-and-they-shall-know-no-fear.45146/ but mostly after reading the Horus Heresy series and now reading the Dark Angels novels this guys are just awesome. unlike most chaos marines the loyalist actually got personality.
So Terran Republic = Imperium, Vanu = Eldar, NC = Chaos? Back on topic, Chaos is very attractive because you get the power armor on top of wizards and mental illness.
