Salutations.
As a long time fan of all things 40k and a modest collector of the actual models its nice to see a forum entirely dedicated to perhaps the most underdeveloped part of the game... the rules!
With a modest number of Marines, Nids (admittedly just the contents of Battle for Macragge ), and Imperial Guard (and miserably painted and modeled Dark Eldar in the more so then usual grim darkness of the third edition) and access to army builder and the internet for everything else I look forward to blazing trails.
I base my codex design off the idea that interesting game play is derived from maximum diversity. I don't believe that armies should be handicapped by their "play style" but should be more focused on their theme.
