My Idea Of A Great Game

So i have been going over ideas from great games and i have one that i think would be really good a lot of theses are probably very difficult to do as they would require software power that is not possible to do. One of these ideas is a open world game that accurately reconstructs the world and gives you every interior on the planet but for security reasons not the same as what it would be in real life. we would then take the reconstructed world and fill it with AI people and allow your created character interact with. we would then be able to create a destroyed reined world and fill it with zombies to create the best zombie survival experience ever! Now I know that this is a huge type of game and with even today's software and hardware would be near impossible but if it is possible and any game creators read this go for it and create the game, i would love to hear your ideas for great games so leave it the comments section and if you like what you see go on and hit that subscribe button! BYE!!!!!
