FloodSim is an online game that lets you control all flood policy decisions and spending in the UK for 3 years ("Whether its deciding how much money to allocate to flood defences, deciding where to build houses, or how best to inform people about the risk of flooding, you are in control.")
At the end of the game, hopefully you won't have put Westminster underwater! Link [Flash] - via Smart Planet, thanks Adam Vaughan!
