Video games and pop culture references go hand in hand. Cameos and easter eggs show up all the time, but rarely are they particularly subtle. I mean, the fedora in the fridge in Fallout: New Vegas was pretty funny, but you didn't have to think to hard to figure it out. On occasion, however, there is an easter egg subtle enough to slip under the radar for a bit. The developers don't indulge in their cleverness, they don't hammer you upside the head with a one-liner and a waggle of their eyebrows... They just throw it in, and if you're paying attention, you might catch it. Bethesda's had a few of these themselves. What have you found?

I'll start with an easy one. Start up a new game of Oblivion and you'll bear witness to Captain Renault dying to save her Emperor. Seems she turned out to be a rank sentimentalist.

Indy was in Morrowind too. Luke Skywalker in Bloodmoon. Three Billy Goats Gruff in Skyrim. I think there's a list on the uesp.
