Wouldn't it be still cool but take up less space if we just had a few videos of the fatalities that the team thinks had the most impact and all the versions of that fatality. They'd be like the bios from MKD and Boon would tell us about how the finisher came to be.
There could be the same (or probably less than the) number of Fatality videos as there were bios in MKD - 10 - this would mean that no quality would be sacrificed. Kind of the super-economy version of your idea!
I could imagine, these two would be definate...
SPINE RIP:
This video would tell us about how John Tobias (if for legal reasons it's allowed) came in one day and suggested this for Sub-Zero's Fatality.
What the team thought of the move, it's impact and full clips showing the Fatality from Mk1, Mk4, MkD (as bad as it is, it still has to be shown), and then a clip of the ender version from MKA.
TOASTY!:
This video would show the origins of the infamous Toasty Fatality and how it led to the Dan Forden clip in Mk2. Versions from Mk1, Mk2, UMk3, Mk4, and if it appears as a Scorp-exclusive ender, the version used in MKA.

i DEFFINITLY think there going to give at LEAST one unique input per character trust me man ;) .....in the fan interview boon sed right now there just focusing on getting all the main characters in the game and working on fatalities. plus boon DID say there making unique ones so i dont think anyone should worry about it

The supreme fatality demo should definetly return !!! It's always what I picked after a tournament.

They probably realized Sub Zero's freezing powers had a lot of potential for fatalities.

WTF is with everybody
you all hate everything dont you
in MKD, everybody was like
"We want more costomization and we dont like watching the same fatalitys over and over again"
and now
"we want the shit we dissed to come back"
pick one, and whatever tha mk team does, please deal with it and dont complain once its released.
to save all of us time, please

What's the problem? It's just a video of the old Fatalities and because people would like to see it and have rememberance of the Fatatlities of old, you're having a go at them? Stop!
This isn't about having these Fatalities back in the game, it's just about being able to see them. There was no need for your post.

Edit - nevermind, i misunderstood what I read lol... Yes I do believe that having a demonstration of EVERY fatality throughout the games would be an awesome reward.. and very nostalgic too.

Lol! You sounded very student like just then.

I SERIOUSLY doubt there would be enough disk space to put all that, let alone all those specific options you mentioned.
I might be willing to change my opinion if they threw out all the useless stuff like pictures of the staff and such, although the chances of them doing that is very minimal at best.
Who knows...send an e-mal to them with the idea, for I doubt they would ever think of it on their own.
Though I do admit, with this being the last mortal kombat of this generation and story, something like that would very much make this game very nostalgic and better than ever.

With the Vault being in the game, it's unclear what it is actually going to contain. I hope that we don't get anymore of these staff pictures and other useless stuff. I don't see there being a problem with this kind of thing fitting onto the disc. Space isn't a thing we should worry about, imo. They should be able to fit something like this on, with or without options.

would love this to be a bonus disk or something... primium pack or what not.

You don't know that. Do you work for midway? I do not believe you realize how much disk space just one disc has..

I never thought of a bonus disc. That could work.

Just like you don't know that it wouldn't. Imo, worrying about the disc space isn't something we should be doing. Anyway, comawhite just mentioned a bonus disc and that could resolve this issue with ease and is a good idea as far as I see it.

I do know about disk space, do not say I don't.
Regardless, it's not going to happen..so whatever.
