Some of the dialogue has stuck with me.

People definitely forget almost all of 'em I'm sure, but...
""Ah! Adventurer, I bore witness to your deeds! You...you were amazing. I felt as though I were in a daze, but now I'm fully aroused!"
""If it has eyes, let it not see you. If it has ears, let it not hear you. Be neither where it is or where it means to be, and thereby pass unnoticed."
"Strike fast and strike true, for victory belongs to the bold."

I love that this game, to me anyway, feels like a journey. I have to stop and take screenshots often because so many of the locales are gorgeous, some of the moments more memorable than I expect of an MMO. It's those moments to me like the banquet at Costa Del Sol and paying respects at the Warden's Grave near Drybone(that scenery was gorgeous,) that make me feel like I'm actually a part of this world. For a bit.
