Have you played Metal Gear Solid 5 yet? It has a cool and extensive crafting system and adaptive AI that actually patrols! It kinda reminds me of destiny at times in the sense that it has some similarities like a home base, areas that you revisit frequently, loot to get (In the for of blueprints) yet its done so well that you actually look forward to revisiting places to see what you missed and to try your new gear. Give it a try or watch a few streams.
