Yeah, if you look at TOR outside of a fan's perspective, it's basically a ton of "Hey! That looks like ____." moments. Troopers look like Clones/Stormtroopers only maybe "older" to some degree. Less evolved. Malgus looks a like like Malak, Vader, or countless other cyborg villains. She Vizla looks like not just Boba Fett, but Boba with long red hair and *******. It's a two-fer there since you cover the "That looks like Mara Jade" crowd, plus you cover the, "That looks like Jango/Boba Fett" crowd.
Ships look like Correllian Corvettes, or Sith Infiltrators, or crude Rebel fighters... Sounds are similar...
The game's really designed to appeal to the casual Star Wars fan, while still setting it in a way that you can have tons of Jedi/Sith and it still makes sense. KOTOR wasn't really all that different either. The droids look like less evolved versions of R2 or 3PO, there's battledroids that look like bulkier and earlier versions of those in the PT.
It's a fun game though.
