This seems very geared towards the Rebellion (duh, it's called Age of Rebellion). I just hope that there is plenty of material for those on the Empire side. Some of my best games were played where the PCs started out Empire and then later defected!
While the GSA preview suggests that being geared towards the Rebellion is entirely by design, nothing about it struck me as something that couldn't simply be "mirror-flipped" for an Imperial campaign, despite GSA's remark about stuff needing to be adapted.
