I have the perfect game. However it is on PS3 i don't know if you have that or not. But if you do play fallout 3 it takes place after WW2 but 700 years later. You come out of a vault that you were born and raised in to find the world a wasteland of rubble and broken cars. along your path you come along strange people and characters effected by the radiation. You play at your own pace and complete missions and quest for different people you meet. The game is enormous and takes place near D.C. Tons of guns, the more you play the more your weapons improve and the stranger the quests get. Fighting supermutants, giant roaches, raiders, slavers and any other circumstances of survival. Staying alive is key. Highly recommended and got great raitings in Gamers magazines
