but I've come to absolutely hate the rules for that game, especially the igo-ugo mechanic that hands the game to the first player.
What? I've never even considered that. I've played 40k for 5 years so far, and I have never noticed the first player winning just because they go first. No offense but I think you and your 40k opponents need to learn some tactics.
also, make sure that you're playing an actual scenario, not just having a slug-fest (which is never actually mentioned in the rules)
