I wonder if you get play the leader of a crack Israeli commando team. You could go to a Palestinian village, plant C4 charges on each of the villager's houses while they sleep, then detonate them. As the men, women and children flee from their burning houses you could machine gun them in full GeForce'd-up glory.
Then you could time skip your way through a lifetime of over-eating, become a bloated bigot and Prime Minister, on a pledge that you will bring peace to Israel once and for all... and go kill more Palestinians (by proxy this time, maybe as a real time strategy game). This in turn will spark more suicide bombers, leading to special 'Retaliation' units, such as an Apache attack helicopter or an F-16. These in turn lead to more suicide bombers, which lead to the generation of more Retaliation units, which lead to more suicide bombers... as infinitum.
I think that would be a very realistic simulation. A bit repetitive towards the end, but worth downloading from KaZaa.
Working title: "Ariel Sharon and The Eternal Circle of Hate"
A bit Harry Potterish, but it might increase the popularity of the game.
