I've only had three games so far (and I'm dying for more!). I still haven't got the wife in on playing it yet. I have only played with starter decks so far and I love it. I'm planning to keep playing with starter decks until I start to get bored with it, and then I'll build some decks. Part of the reason is that I don't see much point in building customized decks with only one core because I feel like (and this is opinion only) that I need duplicates of some objective sets if I'm going to improve on the starter decks. If I just mix affiliations from one starter, I feel like the deck will be just as random as the starter is, so I don't really gain anything from doing that. But the randomness of the starter decks is part of what gives it a lot of appeal. Each game has felt quite different because of the variety of cards in each deck. In any case, my order got messed up and my two core sets were sent to different places, so it'll be another week before I have both of my cores.
As for gameplay, my biggest fear was the edge battles. They're just so intense that I knew I'd put a lot of emotional investment in each one and I was afraid of that leading to sour games. However, I've found that they're actually quite fun.
One thing I love about the game is that it's Star Wars and the theme (for a fanboy like me) is so entertaining that I've really enjoyed my games even though I've won one and lost two. I really do feel like the game designers found a way to make it cinnematic. It was so thrilling to strike with my A-wing to take out a TIE Fighter and then have the A-wing make a Heroic Sacrifice by crash into an AT-ST and clearing all opposition from the target objective. I lost that game, but only just. As others have said, most of the games have been pretty close.
The cons: Now I'm not trying whine here, I'm just being honest about my impressions. Both of my Interrogation droids had these strange scratches on them. It's like someone already played with them [gasp] without sleeves! And I really wish the center column in the box was wide enough to fit sleeved cards. I'm not sure if it's just mine, but if I force my cards to sit in that area straight, it bends the edges of my sleeves, so instead my decks are at angles inside the box.
Quite trivial things to be disappointed with, eh? My overall impressions for this game are very positive.
