if you had... like £10000000000 to make a computer game of your choice what would it be?

mine would be an RPG of 'epic' preportions set in post-apocalyptic britain... you put in your post code (if you actually live in britain) or the game assigns you a made up house and you can travel any where in the whole of the uk trying to gather survivors and build up a stable government or just wreck the place... everything will be destructable and there will be few AI players... you have to find safe food to eat/drink, you have to find sources of fuel, your clothing gradually degrades so you have to find new stuff to wear or you get too cold, some cars work and some are death traps
sort of a mix between fallout and oblivion but with no magic/mutations
