never got much of a 40K force happening,but I loved my Plague Marines,so gloriously pustulent ^_^
I was more into good old swords and sorcery.specifically necromancy.extra-specifically Vampire Counts (the edition Just before the current one was my prime)
favourite unit would hafta be
this guy right here.-note-this is not a picture of MY model(mine was not as well painted for a start), I nabbed the image from Teh Interwebz(tm)
by the numbers:
1,015 points worth of Vampire Lord Zacharias:The Everliving,complete with Zombie Dragon.it's worth noting,that for a while,buying this hefty model was the only way of getting a citadel zombie dragon
fills 1 Lord PLUS 3 Hero slots in your chart...but so worth it
all 6 Necromantic spells,plus a free Dark Hand of Death every magic phase.
1 free Dispel scroll per enemy magic phase
all 6 Necrarch bloodline powers
and a 4+ ward save.
granted,these will not mean much to anybody unfamiliar with the previous edition of either WHFB itself OR the army book in question,but I was quite proud of being the only person that I had ever met that owned and used this model.granted,it's not worth taking him in an army less than 3000 points,but the look on an opponents face when plonk a badass like this on the table is absolutely priceless.
