So yes, like Nemurils post shows there are pilots you don't have and equipment you don't have if you don't buy the expansions.

Wedge is worth getting xwing expansion for. If you play rebels, you want wedge.

Thanks everyone!

The Tie Expansions is awesome because of Howlrunner so definitely get it too.
