Lets say you had a 2500 point army between 4 people. Each on a team and against the other. Lets make it 7 turn min Annihilation and pitched battle.
What armies do you think when paired together against another really awesome team would make for a really epic game?
I personally think that a Tau / nids Vs. Necron or Eldar or just another army that relies on stratigy and Orks.
Of course another really good one would be IG and Space Marines vs Chaos Space Marines and Nids.
Basically what team based game would you think would make for the most fun?
