Brainstorming my Game

Throwing around ideas...

• What if its like a comic
• what if you build a narrative
• what if its theme is sci fi
• what if you have to solve a mystery
• what if I draw inspiration from Clue
• What if its like choose your own adventure books
• What kind of goal would a narrative driven game have...
• what if the game rewards you for sabotaging your opponents
• what if it has action/narrative cards players must battle over
• what if one player plays as the hero, and one as the villain
• what if those two players must play for districts of a city...
• players win districts with narrative cards
• what if you play as a detective
• what if you must collect evidence, but it might be false evidence?
• you can get false evidence from other players, they can tamper with your evidence (cards?) 
• what if the game board is round
• what if you advance by landing on another player
• what if you can counterattack another player with a card of their gamepiece/color?
• what if you have to get exact number with dice
• what if you have to rely on another player to advance, but they don't know it?

I was focusing on theme, what was the story of this game? I couldn't envision a game-play without there being a cause... a narrative or goal of a person or creature instead of game-play rules and a core game-play idea. 
The last of these ideas was a bit of a fever pitch of an idea. My brain seems to have snapped into thinking of solid game-play and not theme at the moment, although soon they will both be important.
