Of course, movies are highest order of G-canon and LucasArts has whole division dedicated to determining what level everything is in 9-level system.amaranth_dru said:Since every EU novel/game lore has to be approved by Lucas, I'm pretty sure its canonical. There's strict guidelines for writing in that universe, so I'd say its definitely canon. Although the SWOTOR lore irks me a lot since there are Chiss present in that time period yet they claim in the current timeline to have never had contact with humans until Thrawn/Car'Das met. Of course that could just be racial obfuscation...Evil Smurf said:the extended universe is not cannon :/distortedreality said:Elder Scrolls, Mass Effect and Fallout come immediately to mind. Deus Ex as well (although not on the level of the previous three).
The KoToR series has a ton of lore which wasn't part of Star Ware lore previously I think.
Sid Meier's Alpha Centuri has a decent amount of lore
Anyway, if it weren't canon then Lucas wouldn't care what people wrote.
