If you go back even further in time, you would find that The Sims diamond has a striking resemblance to Tomb Raider's save crystals, only they were blue instead of green.

People complaining about more role-playing elements being added to a role-playing game. Go figure.
Coby does have a point there, though I'm inclined to think that people will complain regardless of what's being added to the game. Hearthfire kind of proves that point by the fact that it is based on popular features from the Game Jam video, yet is receiving some hostility anyway. Hearthfire obviously isn't for everyone, but looks decent enough for those interested in it. That pretty much applies to all DLC considering the vast audience of TES, and by the fact that everyone has their own ideas on what should be added to the game.
