well nobody knows for sure, so why don't you wait until monday and find out, none of us have played the game yet, so, there is no way we could know

I knoe it's been ruined by that god awful character Shujinko.

from the looks, screens, and guessing.. it looks like u can walk around anywhere, and maybe u can punch people for the heck of it but i dont think so since u need to talk to all of the people to unravel the story line. graphics do look bland tho. i dont think u gain speed or anything like that, i just think u gain moves. also i dont think that u can use him early. u have to beat the full konquest inorder to gain him. all of this is just speculation on my part. none of us really know for sure yet.

"Will it a action RPG, can i just walk up and kick somebody?
All the MK charecters ever will be in it, but will they do special moves?
Is there a story to it or just a glorifey theme park?
do you gain strenght and speed and stuff, like stats, or does he just get old.
Can you export him at anytime?"

Yes, we've seen in videos that Shujinko can smack people as he runs around- he knocks one guy to the floor, and coins appeared.

I reckon the MK characters will have special moves...otherwise how could they teach Shujinko what they know?

There is a story there- leading up to the Dragon King's resurrection, I suspect- but the main purpose of Konquest is to teach you the fighting styles. There's definitely a theme park element...

I'd imagine he just looks older as the game goes along. Although, obvious;y, he learns different martial arts styles.

When you say export... ? If you mean, will his younger selves be playable in the Arcade mode or online, I'm guessing NO.

I'm just hoping that you don't have to do an excercise is pulling off 40 button combos like you did in MK:DA to accomplish anything just to earn a few coins or whatnot.
