What kind of ideas? if your talking storylines, Stone Cold vs. The Rock is fun to do.
I normally let Universe mode tell the story for me. If im booked say as the Rock agains't Dolph Ziggler. Then i say beat him, but next week universe just puts me in a different match. Ill set up another match to keep the storyline going. Then as per usual, the game will not book me in a PPV match. So i put myself in one, continuing the storyline.
Sometimes this will make the game auto set one up with cut-scenes. So the best thing to do is keep putting yourself in matches with the same opponent, and changing them up a bit.
Stone Cold vs Rock can be quite interesting though!
