It's also worth pointing out that BG1->BG2 wasn't exactly seamless. You could import your character and some gear, but the game completely ignored your BG1 playing companions.
Has there been a game at this point that had save ports? I can't think of a game that would do that before Mass Effect.
Frankly I don't think there was enough major decisions in BG1&2 to really demand continuity.
That said I would appreciate it. I don't think it needs to be a big feature but something like in Kotor2 - where we can express who Raven was. I don't think it has much, if any, impact on the game but is a nice touch.
