Well Star Wars:TOR is a MMO about 300 years after the KOTOR storyline. The only thing that'd be tough with KOTOR 3 which the Mass Effect story is doing is bringing that storyline over like they did with KOTOR 2. It'd seem kind-of odd to tell that Revan saved the galaxy or didn't and then answering what the Exile did: "Wait this jedi destroyed Malachor V? How would you know that, no one ever passes by there" Or something of that nature, hopefully they work it out when they make it.
