I saw an PC game called Commander in Chief, in the purple toy shop before coming into work this afternoon. The premise seems to be taking control of a country and deciding military and economic policy etc. I can only see one review on the rainforest site but it got 4 stars so might be worth a look.
Trouble is, I could see me nuking all the trouble spots, floggin' and hangin' the domestic populace who cause trouble and generally being a bit nasty, with my bit of power!
On a more mundane level I see Steam have Prison Tycoon 3 quite cheap, might be worth a look, specially kitted out Death Row all utilities Electricity and Gas!
