Well for me personally I never actually had the fortune of completing the whole thing successfully! 3 times in a row! [img]redface.gif[/img] due to a getting a virus twice and having to reformat and then getting a new comp and losing the saved file. And now this time making the crucial mistake of killing the wrong character in the wrong place at the wrong time!
Other than that pretty much everyone else has said it for me. Its always different the second time around if you choose a different class (different weapons, skills etc) adds variety and having different NPC's in your party. I wanted to cont through importing the same character from BG all the way through to ToB.
Its one of the best RPGS ever made!

I clicked in the wrong place sorry
should of been in the post of ORBOST 'why do you still play BG?'
