If you wish to critique my suggestion, please refrain from saying this is not possible or they will never do this, for it is up to Bethesda if it is possible or not.
A seed generated coop post apocalypse game ( fallout or not fallout )
For starters this game will have no story, this game would be centered around you and your friends starting a game and building your own town. Using a creation mode similar to fallout 4, except much more expansive. From environment restoration to town building, you start off with nothing and eventually go on to run a massive settlement. Gathering materials either by hiring people or by doing it yourself. Rebuilding the environment around you is very rewarding, as wood is normally scarce and is used in most low to medium grade housing. Each landscape has its own rewards, crops for example would have bonuses that increase if you fertilize some flat land and rocky landscapes could be used for high quality mining settlements. Landscapes may include flat land, mountains, hills, dying forests, radioactive fields, and each landscape could have a set of modifiers to it, like bandit country, or radioactive wasteland. Your job as a player is to create attractive settlements for NPC's to live in, and keep them living there by gathering and by providing basic needs like water, food, beds. You also want to keep your people well armed. Building and upgrading an armory not only provides your settlers with guns, but also gives you a place to buy and sell. Buildings like these may include armory, armor vendor, clothing medical supplies, traveling merchant, resource merchant, stockpiles, greenhouses, management buildings, guard posts, etc. A management building is the place where you can direct each and every settler in one place, rather then giving the orders to each settler individually. Each landscape has its own set of hazards and enemies. Enemies consist from various wildlife both mutated and not mutated to bandits and robots.
Well I am finished, please write what you think, and if you have anything to add to the game suggestion please comment below
