While it probably deserves it's own thread, I would say of the 3 Fleet based combat system I've played over the years (Star Wars: Armada, Battlefleet Gothic & a small amount of Firestorm Armada), Star Wars Armada has the best rule set.
It manages to do pretty much everything you wish it to in a relatively intuitive way. It's excellent in the way it handles different shields/weapons per firing arc and the feeling of how much a behemoth Star Destroyers are with terrible turning circles and longer command structures. The firing first works perfectly and neither of the other 2 really give you that sense of scale.
Managed to get in 2 games yesterday, the second of those against someone else with a copy so we got a larger 300 point game. There were plenty of rules mistakes in the first game, but by the 2nd we were fairly competent and it sped up to a decent pace.
I've not played X-Wing, but am reasonably aware of the rules and I would say Armada is heavier, more fiddly and a lot less cut out for tournament play. The amount you need to pickup or move miniatures out the way to do movement measuring and shield adjustment means the game is less exact and that will always put tournament players off. Versus that it offers a very different experience as hoped and I would say the miniatures are little better (I own a couple form X-Wing). Also at 300/400 points, it is easily going to be a 2 hour game.
My biggest issue is the price, there isn't an awful lot in that box even is the painting is excellent for a mass produced game, but still, I'm happy with the purchase because the game play is so well done.
