In the next few weeks, we'll be playing a series of games in a round robin style format or tournament. This will be purely for fun, of course. I'll be using a 30k Alpha Legion army list and will be testing out a list that I've never used before.
However, one entertaining rules query has already come up. One of the other players will be using Codex: Chaos Space Marines. Without thinking about the background fluff too much, how will Veterans of the Long War special rule interact with a 30k Space Marine Legions army list?
I am personally going to suggest a ruling that it'll have its full effect. It seems only fair. Regardless of whether I declare my Alpha Legion to be Loyal or Traitor, the wording of Veterans of the Long War is such that it effects "Space Marines". I regard that the pre-Heresy (certainly) and the immediate post-Heresy Alpha Legion (arguably) were still Space Marines in effect and were not highly influenced by chaos until later on.
I'm wondering if others have come across this before (or other interactions of 40k and 30k rules) and what they've done?
