I'd have to say my favorite inserts have to be from the original Final Fantasy for NES. That game came with a lot of awesome stuff that really made you feel like you were in for quite a ride before you even turned on the system. A partial strategy guide? Not one, but TWO double-sided charts!? It has a lot of nostalgia value for me, and now I will tell you why, even though you didn't ask.
I remember my cousin Brent had the game when I was little, and I was very intrigued by it. I would re-read that manual/strategy guide over and over. Then he let me play, but made me SWEAR never to go to the Inn as that would overwrite his save game. One time I ignored him, because I thought I was smart, and decided that if I didn't hold reset while turning off the game, it wouldn't save. I was wrong. I was a stupid kid. I overwrote his game. Brent was pissed.
Oh, well. He was only at the Earth Cave anyway. No big loss.
