Are you telling me that you want me to do it? Or do you think you can pull it off?
Because I can think of right now how I would do that game and I could do it successfully. The closest game that matches what you want would be the Sonic mafia. It had illustrations every day. A prize of good value. The storyline was just random to make a joke for most deaths. It's a fixed time limit since someone is going to win at some point.
Then there was Star Wars mafia. It had a scoring system in that everbody had a value and if the bounty hunter killed enough people and collected a high value amount, he could spend it on a thermal detonator.
Anyways, I'll tell you right now what I would do for your A mafia game and you can tell me if you think that it would meet you dream.
I mentioned once before doing an RPG themed mafia. I could make a soaring storyline for it. Something like Mafia X. The F-Zero mafia. That was probably my best story and even then, I could do better. Really plot it out. Since I'd have story points, I'd be ready with illustrations. I could throw in a few prizes.
In my crazy Funhouse mafia, Mafia 12, I experimented with a time limit. I could ensure of the game following a strict time. I could make a scoring sytem also. I could do something along the lines of Mario Kart mafia where people are a certain value to kill off, ala an RPG or I could follow up on my bounty hunter experiment.
Hmmm. Now that I have a direction, as soon as this mafia wraps up, I'm planning this triple AAA game.
