What I've found interesting about the game is that non-wargamers have been willing to try it entirely because of the franchise. This is great for me as I get to try and convert more people to wargamers! It is interesting to see their reactions as the game is pretty complex and as a wargame/minature game without a "board" it's very different to what they are used to.
I've been playing 180pt games using pretty much the suggested rebel/empire builds per the FFG website.
My experience has certainly been people try and take out each others squadrons first, but it's pretty clearly because the rebel's want to get their Luke/X-Wing to attack the destroyer. Luke's ability is great but on it's own is nevery going to be enough (with the 180 point set up the destroyer can repair two dmg cards in a round after all).
It's true I've never seen the Imperial player use Tie's like this, but that's because either they've blatted the rebel ships comphrensively with the destroyer or because the tie's are downed quickly by the x-wing.
So far I've seen 1 rebel player victory, but that was a bit lame, the two new players flew around each other and no one scored any sort of hit on the other. I've never seen the Imperial lose a ship in my games and my biggest "thought" concern is that it's too hard for the rebels to pull this off at 180 pts and it's really offputing for new players.
This is because I find new players don't care about objectives and just want to shoot each other... I guess it's my fault for not pushing objectives on them eh?
If you're playing 180 point intro games, I would like to suggest switching to the Gladiator Star Destroyer. The VSD is pretty hard to take down at this point level, while the GSD is a little more evenly matched to the smaller Rebel ships. It will give a good gaming match up, with the added benefit of ships probably blowing up more often.
