A Wookiee army, though, would make the Star Wars universe seem a bit too condensed. Ewoks made Endor feel like another new discovery, both for the viewer and also the SW characters, themselves. The SW characters didn’t know what they were encountering when they landed there. If it had been a Wookiee planet that the Empire had just decided to use for their base, then it’d be like: OK, so in the SW universe there are primarily humans, droids, and wookiees… and the rest are b-grade props.
