alot of it is mostly launch kit videos when it came out in the arcade.The other ones are making of the game and some interviews.It does actually go into more depth the the history video that we all have seen.But the videos you will see are old and nothing new.But its worth watching nonetheless.

MK2 only has one video - The launch kit video

MK3 has tons of videos - Making of videos and the launch kit video for it

I thought that MAT 2 was worth getting for the bonus vids alone. It's great watching all of the little subtle differences in the prototype version of MKII, such as "Otomix" written on the side of Cage's pants, the "blood mist" from Kitana's "Kiss of Death" instead of the usual guts... not to mention these big as Asian soldier statues in the background of the Sky Tower stage.

As for MK3, there's about 20 minutes worth of behind the scenes footage, much of it not even shown on the "Behind the scenes" video for download on this website. More interviews, including with Kerri Hoskins (yum), Carlos Pesina, and Sal Divita. Look out for about a minute worth of snippets spread out of Pesina and Divita fighting (literally, but not for real of course) over who is better: Raiden or Sektor... at one point with Pesina wearing the Raiden hat and Divita wearing the Sektor helmet, heh heh.

Trust me, for twenty bucks, it's worth it for these rare videos and a damn near "arcade perfect" edition of MKII... MK3 isn't too bad either.
