I remember playing Metroid and making it to one of the bosses just by exploring the game. Can't really go back to it as I would get lost without a guide.
If this plays like WWF No Mercy then that will probably be good though I was never any good in story mode as it has hell. The AI would always low blow me and when I thought I had them, I would lose. Hopefully it ain't difficult as those games were easy to play and fun.
