Anyway....I do like Easter Eggs, when I recognize them (I don't always know the references)....culture reference gravestone epitaphs you can read if you bother to click on them, simple NPC names/encounters(hahaha, look, it's that Drow in BG1!), or even just secret levels that open if you find items/do things in specific order (Dungeon Siege1-2, Diablo2...).
