Me and a friend of mine recently played a game with his orks versus my chaos space marines, with a bunch of Khorne berzerkers, and it was surprisingly a lot of fun for the both of us. We play to win and usually if one of us is winning the other is pissed off so that's why it was odd for both of us to be content. I got to thinking about it and why it was so much fun and I think I figured it out. In my opinion it was our choice of army I can't remember the exact list but I'll list the hard hitters. He had a wall of killa kans, big mek with kustom force field, Wazdakka and some bikes, and a bunch of boys. I had a vindicator, defiler, 4 squads of Berzerkers, Tzeentch lord in terminator armor and daemon weapon, and Tzeentch Terminators.(the one with chain fist was the game winner) There were a lot of epic moments like when he took out my vindicators cannon and wrecked my land raider with one shot, or when three berzerkers ran off into a blob of boys and piled the bodies sky high. I love the chaos versus orks because it’s like two crazy people arguing about who's crazier. And with my Tau I love playing against blood angels. They are so fast that sometimes they're too fast and easy to bait and catch in traps. But with my Tau I HATE playing against my pals Ultramarines, they advance steadily and tighten up on me like a noose and it's hard to focus my firepower.
So what does the community think? What army is the most enjoyable to fight against?
