Life is currency huh? I might as well make a game based off the movie In Time, where time is literally your life. Run out of time, you fall dead. People gamble time in order to gain more time. Sucks if you lose though. I think there's a social message there about how we use our time and time is money and how some people literally live minute to minute in order to make it in life.

In any case, I don't know if I will go that route though it's a good exercise in thought. I'm gonna spend some time brainstorming and see what comes up. Best of luck to everyone!
