I've always been intrigued by customizing my own things in games. I remember the Juiced 2: HIN game I rarely ever even played the game I just built cars. I like that we'll be able to build housing, settlements, weapons, and power armor in 4. I think it's always been a "this would be nice to have" feature from the older games that people modded in. And it's not like rebuilding doesn't have a theme in Fallout, you can see settlements in every game. Only now, we get to build a few to our liking. I can't see why a new completely optional feature would really bother anyone
