i have had a blast playing and crafting, though i have noticed a few things that may need attention, or futher flushing out...
i would love to see a DLC or something that has more crafting features, and perhaps fixes some of the problems i have seen thus far. one thing that bugs me is even with a roof on your structures, rain still comes in and makes every floor and item glossy, as if wet reguardless of how many stories you build.
i think a landscaping tool would be very handy, even if you make it so i have to use a shovel to dig up dirt and move it, would love to have more grading ability, and some things should be able to follow the natural grade, like fences and such on a hill, no need to start on ground level and after a few feet being 4 feet off the ground cause it it snapping to the other post.
which brings me to another point, more active control of where wall sections or fencing go would be nice, maybe a snapping on/off setting so you can easily place sections of wall of fence if your going around your settlement instead of following the line and then trying to adjust for the boundaries and not being able to.
as i said before i love the game, just think thinks could be a bit more, and i know some people want more things to build, streetlights is one post i saw, but outdoor area crafting items would be awesome, maybe a ground tool for in your settlement for gardening area, making the ground easier to see in the area meant for gardening. and we have generators, what does a guy got to do to get a weed wacker or a lawn mower, or even the companion robot to trim up the non-scrapable weeds and crap, *grins*
