I was digging through some boxes when I stumbled upon a copy of the Forza Motorsport (XBox) demo disc. It's in a standard XBox case, and it included an XBox Live Arcade disc that says it contains Ms. Pac-Man. I'm curious to know two things:

One, did you get the demo for free or did you get it when you paid for a Forza pre-order? The box says something about pre-ordering the game.

Two, what's up with that XBox Live Arcade disc? I can't find any information on it anywhere. Was it included with other games, or with Live subscription packages? And what's inside that disc? (I don't own an XBox so I can't play it.)
