Re: Just finished KotOR for the first time...
Only the Star Wars films are true canon. Everything else is only canon as long as Lucas says it is and he can de-canonize it at any time, as he did with the original clone wars cartoon. The canon Revan is a lightside male and the canon Exile is a lightside female but Lucas could de-canonize both games if he wanted. Star Wars canon is more loose and not as clearly defined as Trek canon.
So KOTOR is canon.
Do you need a Venn diagram?
