So I haven't finished the story for fallout but I thought of this idea, maybe there could be a dlc for a war in the commonwealth. It would be the minutemen, brotherhood, institute, the railroad, and raiders all at war with each other. Our character would choose a side and become in charge of the group. We can build our "army" and send them where we want to defend settlements or to attack the enemy with us. They also ask us to do things that will help the cause. If we are gone from a settlement too long and we didn't set up a good defense another group will attack it. There are also a lot more settlement attacks. We can build more settlements and we would have more building styles and equipment. There could be more turrets and more weapons. Depending on who we join we could get different things. If we choose the minutemen we can expand the castle to include the city that is right in front of it and we can get more minutemen. The minutemen are also able to unite with another group but the raiders and the supermutants are more violent towards us. If we join the brotherhood we get more weapons and stronger soldiers, but the ghouls and supermutants will start attacking more frequently. If we join the institute we get the most advanced tech but the railroad and brotherhood work together to destroy us. If we join the railroad we are able to make underground settlements and the people are able to do stealth attacks but the institute pays closest attention to us. If we join the raiders we are able to use fear to get settlements to join us and the raiders are able to steal for us. But all groups are more violent towards us. In this dlc we could get more missions that are for making the Commonwealth safer. Such as making the roads safer by making defense posts. There are a lot more ideas that I have but I will leave at this. Oh and if you won't consider it because of when people are done with the dlc people won't have a reason to play but that isn't true, you can come up with some things that happen afterwards like the animals are more aggressive, the raiders start working in secret trying to take out you among some other things. It is just an idea but I think it could be a great addition to the game.
