I mostly agree with Commas about rumors and dead-ends, but if we were to play as the Exile again, I think the game should allow you to start at like 30-35th level and have an allowance of Force Powers to choose from. That way, you could really customize according to what your favorite Exile version was in TSL.
As for M1911A1's idea of voiceovers, I agree. Even though they were minimal in K1, I still missed the occasional main character lines like "I'm here" and "damn!" in TSL.
