Honestly, I don't think Lego know the difference. Besides, it'd probably be cheaper for them to put everything under the one TOR line. It's not that innappropriate, a lot of the themes, characters and vehicles from KoTOR 1 & 2 cross over to TOR. Revan was a nice start, sure. But there's so much room for more sets. Personally, I'd like to see the Endar Spire, but don't think we'll ever see the scale I'm thinking of! They've barely scratched the surface on what they could sell from TOR, though. I'd would love to see the Phantom for the Imperial Agent ship made into Lego, especially with an interior. It would also be great if they released battlepack sized sets and included all 8 classes from the game as unnamed minifigures, much like the Jedi and Sith included with the Jedi Defender. Most of the walkers and ground vehicles in the MMO are unfortunately nothing special. While reminiscent of both Republic and Imperial walkers, but they're very blocky and not very memorable so probably wouldn't sell. I honestly think the setting for The Old Republic is much better than the story through Episode 1- 6, it's much darker. Palpatine's Empire is a pretty laid back by comparison...
Also, Hi! I suppose I'm new. Had to weigh in on TOR! But I've been visiting this site for quite some time now :P
