Players of the original Star Wars: Knights of the Old Republic (KOTOR) will remember that during the course of the game you pick up a handful of characters that help you with your adventure. And really, several RPGs do this: Mass Effect, Neverwinter Nights, and others.

What TOR does to sweeten this experience though is to take all the crafting that the player usually has to do (from making armor to cooking meat), and lets you assign it to up to three of your companions. In the early levels of the game when you only have one companion this isn't a big deal. But later when you get three or more companions and can send them to get things for you while you're off adventuring... well... that's awesome.
