While I love crafting and base building in other games like Fallout 4 etc, I think it doesn’t mix with this game very well. It’s supposed to be a story driven game where we roam through an area that’s been taken over. It’s all we can do to suspend disbelief enough to accept that small arms would work against mechanical foes, now we should be able to craft grenades or build up fortifications that a hydraulically powered machine couldn’t simply rip open in a moment? No, the game is about suspense and sure, there are long periods of running around doing nothing followed by tens of seconds of terror when you get in over your head and end up against three squads of hunters or something. But it isn’t Fallout.
I just don’t think it works here man. But remember, the game is still very new and more content will be added. Maybe wait and see what the devs do with the story and everything else before looking at crafting?
