I'm guessing you just want to play the mode for the two characters, otherwise why the hell would you want to skip the cut scenes? The story is actually really cool and very well done. I love how they've gone into details about all the characters (example; the current Sub-Zero's real name)
80% of today's 'gamers' are puppets, told what and how to play, void of any imagination and creativity. Cut your strings and be free with me.
