Hey, thanks for many replies
I found so far that people of a specific profile are playing games like Mafia. Same people tend to like board games.
I don't like board games. Because, everytime I play, someone gets angry at me eventually
And I am only taking the most rational actions to win. No storytelling, no emotions... Pure ratios of win/invest.
I am generally interested in Game Theory, optimal strategies and stuff... So I approach every game in such way.
I feel that most board games (and Mafia also), are not devised for players like myself. (I developed interest in Mafia 'by accident').
When I play board games, I tend to find a dominating strategy that is either not intuitive or not in accordance with the story behind the game. When a game has a single or too few dominating strategies, it is broken.
In game theory, this would be called that the pareto optimal front is too small. In layman's terms, a game should always have a rock-paper-scissors component, so that none of the strategies is dominating all the others.
A game that is broken in this way can be fixed in two ways:
1) prohibit the dominant strategy
2) change the game so that new strategies emerge or the current dominant strategy becomes less profitable
This is basically a choice whether you will reduce the number of strategies or increase.
The successful (popular) games tend to choose number 2. One example is chess and the "en passant" move.
So, to get to the point...
If I were to play day-to-day mafia with my colleagues at work and one evening one of them comes to me and says: "Look at my laptop, it says here clearly that I am innocent. Show me your screen so that I can make sure that you are innocent too."
And even if I am innocent myself, I am supposed to report him? And even if I report him, how can anyone be sure that I am not stating false accusations?
This is just... not a game. Not in the purest meaning of the word. It is a group of people embarking in a fun story together and they are enjoying the story more than the competition.
I believe this is why the game is only popular with the specific profile of people. I kind of feel that the game has a great potential (both as a fun competitive game and as a platform for research in psychology, sociology and game theory) but because of these reasons it has always retained the reputation of a childrens' make-believe game...
