I'm a sucker for games referring other games, especially when those games being referred are awesome. It also helps if you're a nerd for that game.
Take, for instance, Fable III. In it, it references The Legend of Zelda in a strangely obscure way. In the Mourningwood Cemetery (just beyond the Mourningwood Fort, a story-related mission), you'll find a shit-ton of graves. You'll find a small handful of references in there (I think I even found a Pokemon reference in there; "he died by going into the long grass"), but they don't beat Zelda's reference, wooden sword and all.
