I have recently convinced a couple friends to get into warma-hordes, as my collection has been collecting dust this is great news. It has been quite awhile since I've touched warmachine, I only own the original black and white prime rulebook. As this rulebook is most likely outdated, where should I start?
I noticed there are plenty of rule books out; wrath, vengeance, reckoning, prime. I want to be up to date on current rules so that when my friends are ready to play there aren't so many speed bumps. I was thinking about getting just the prime book, but are the others required?
Also some of my friends are getting into hordes, what i've heard is that they follow the same rules, except hordes has some minor differences with their beasts/warlocks. Would the prime rulebook work for both, as long as they get the hordes digest rules in the start pack?
