I read this article here: http://www.gamesradar.com/fallout-4s-crafting-system-explained-bethesda/
and I couldn't help but notice the pic of the Bayoneted Pipe Rifle. I can't help but wonder how many different variations of that gun I can make ... and if any of them are better than the rifle I find on the next bandit I kill. I mean sure it's cool that I can make a thousand combinations of guns, but if there is nothing really significant about what I craft over what I can just buy or find ... isn't just kind of fluff with no real substance.
I've played Divinity Original Sin and that game has a crafting system that is just overkill. You can find wheat, grind the wheat in a mill to make flour, add water to the flour to make dough, put an apple in the dough to make apple in dough, put the apple in dough in an oven to make an apple pie, which you can then eat for very little benefit or sell for next to nothing. The point being you do all this crafting and all this work to make an item that is basically worthless. And what makes it worse is there's an apple pie sitting right over there on the table you can just grab now and avoid all the crafting and hoarding.
My fear is that FO4 will end up like this. That you can collect hundreds of items to make thousands of things that in the long run are not any better than what you can just find laying around. I think I would rather there were only a hand full of items that are very rare (as are their ingredients) and very useful once made, or at least a happy medium between the two. So far FO4 just looks like it went off the deep end.
