Okay, so if you're at all like me, you skim the rules, do a walkthrough game, read the rules and start playing. Then, after a couple of weeks, you get some downtime where you can go through the rules with a fairly good grasp of them, then, "Bam!" you find a simple but important rule or concept you missed. Well, this is the thread to put those, "Doh! How did I miss that?" moments!
For me, it was the Command Phase section, last sentence of the first paragraph, "Each player may issue a number of Orders equal to the number of ø he rolled in the Initiative phase (with a minimum of one)."
Its the last parenthetical phrase we haven't been playing. We've been playing if you rolled all blanks for initiative, your commanders were all sitting on their thumbs unable to make a decision, and no orders were issued. Guess even Analysis Paralysis battlefield commanders can at least get out a single, "Hey you! Go do something over there!" order in the Command Phase.
What have been your, "Aha!" moments on your second, more thorough read-through of the rules?
