I haven't seen much homage in The Elder Scrolls Online, but I'm not sure it isn't there (I won't get every reference), or if it's just that the game world is so huge. Also ESO doesn't have much room for homage in that, since it has five previous games that the writers need to either build from or build towards, there is a lot of lore and culture that is already set and needs to have a presence in the game.
In the most recent expansion preview, one of the quest characters says, "I'm as fast as a leaf on the wind..." This is reminiscent of a line from the much-loved series,
Firefly, where
the character Wash occasionally says "I am a leaf on the wind" when piloting the ship through whatever danger has come about at the moment. I'm not sure if it is actually a Firefly reference, the two might just be inspired by the same thing, but, I think it's a good chance.
But I also ran into a skeleton hanging from the ceiling in an icy cave, along with a sword which was nearby stuck in the ground.
This is a copy (of sorts) of a similar cave in The Elder Scrolls V: Skyrim, which itself is homage to
Star Wars, where Luke is hung up in the cave ceiling (as a snack) and has to use the force to get his nearby light saber. (I didn't get the sword in the photo though.)
