Game References Within Games

[Moonface]

I don't know how many AAA games do this sort of thing anymore, so it's probably more of an indie thing nowadays, but what neat references have you seen in games that are for other games from a different series?

One of my favourite ones is the three-way collaboration between Naughty Dog, Insomniac Games and Sucker Punch back in the PS2 era where each would reference the others games within their own. Ratchet & Clank 2 is the one I think did it the best, with the main menu showing Ratchet playing Jak & Daxter, Jak 2, and Sly Cooper on the TV if you left it long enough to cycle through to those games. Then during the game itself, images of the main characters in those aforementioned games can be found in certain locations, and in one of the later levels of the game instead of collecting a key item normally, Ratchet & Clank recreate the iconic pose Jak & Daxter make when collecting a Power Cell in their first game.
