A few years back, I decided I'd recreate the GW studio Blood Angels army from 1991. A few days back, I finished it:
Based on the then-current Rogue Trader force building rules, the army was detailed in White Dwarf issue 139, along with a painting guide, and later appeared in what I believe was the first Warhammer 40,000 battle report in issue 141. The pict-capture below shows my army alongside the inspiration. I hope you'll excuse the lack of goblin green on the bases!
Alongside its Eldar and Ork counterparts, the army appeared numerous times, notably in issue 166; when a battle report to showcase the release of 2nd edition Warhammer 40,000 saw Captain Tycho felled by an ork psychic blast. That period – from 1991 onwards – was when I got into the hobby, and this army was the seed for my enthusiasm.
I do like a bit of 'high-concept' in my hobby; so rather than simply swapping things out for their modern equivalents (Intercessors in place of Tactical marines, for example), I've converted the relevant figures to better match the modern scale. I've got a lot of fondness for the originals, so I wanted to make sure my figures paid homage to the classics.
In essence, the idea was to create the army that Tim Prow (who painted the original army) and Andy Chambers (who put the list together) would have made had modern manufacturing methods been available at the time. Good design, after all, is timeless. Balancing putting my own spin on things with them being instantly recognisable was key.
