I picked up two more Booster packs today, mainly because my collection was heavily leaning toward the "Rebel" side. When I start playing other people I want to be able to have more than one good squad in case they want to use light-siders. Here's the contents of the two boosters I purchased:

"Alliance and Empire" Booster
Rebel
8/60 Han Solo in Stormtrooper Armor
17/60 Rebel Commando
22/60 Twi'lek Rebel Agent
Imperial
34/60 Stormtrooper
Fringe
40/60 Duros Explorer
50/60 Nikto Soldier
Yuuzhan Vong
58/60 Advance Agent, Officer

"Champions of the Force" Booster
Old Republic
4/60 Jedi Sentinel
Sith
15/60 Sith Assault Droid
Republic
29/60 Kashyyyk Trooper
30/60 Mas Amedda
35/60 Republic Commando - Scorch
Imperial
46/60 Coruscant Guard
Fringe
59/60 Ugnaught Demolitionist

So, I picked up the Coruscant Guard and Mas Amedda to add to my "Imperial" squad, but also acquired enough "Republic" characters to be able to form a squad for that faction as well (I still have to supplement it with one or two "Fringe" characters). The Han Solo piece obviously gives even more of a punch to my Rebel squad.

I found a store locally whose owner told me that people play there almost every day, but I'm playing some games against myself first so that I can figure out which configurations work best for me to ensure that I don't look like an idiot when I go (even though I'll look like an idiot just for playing the game anyway).
