Addiction comes from wanting to beat anyone deemed weaker to gain experience points, level up or simply get more money.
The catch about Mafia Wars is everything is based on a timer. Whether it's the energy, health or stamina meter, time is of the essence. A key characteristic to the game is patience. To monetize the game, developers offer a way to buy points to refill meters but it'll cost at a minimum $5. Gotcha! It also encourages interaction with strangers which is the point of social networks.
For some the game may have gone stagnant. Leveling up and mafia domination can get old. To spice up the game, developers recently started to beta test a change in setting: Cuba. While it isn't available to everyone, select few have been racking up more jobs and exploring the new aspect of the game.
