That's a gorgeous army! Have you put it together for the hell of it or is it tailored towards a gamesystem? 
I just wanted to do something Fantasy or Lord of the rings again after long time (Back to the roots). As i love beautiful terrain as much as beautiful figures, i had to do it smaller than 28mm and i found the Eureka 18mm and Magister Militum Blood Dawn figs. I had only painted a few when Copplestone released his first barbarians and they fitted in perfectly (although not very LotR).
When the first 20 figs were ready i played "Song of blades and heroes"
With 60+ figures painted i moved on to my version of "Triumph & Tragedy" (Triumph,Tragedy & Trolls)
Now i have over 200 done so i use "Hail Caesar"
