Here is a thread from two years ago on the same subject; I figured that was large enough a gap to warrant a new thread.
I just recently started looking at the Planet Strike expansion, and I think it seems like a fun new way to play the game. With 6th edition right around the corner this is obviously no time to dive into an old expansion, but I must say I am curious about what you Warseers thought or think about the rule set. It's been almost three years since the book was released: is anyone still playing it?
From what I've seen of it the damage the attacker can dish out using orbital attacks seems a bit over the top, but I have never played a game using the rules myself. What are your thoughts looking back on it?
