So I think resource sinks that don't really give you much but are cool/funny would be very beneficial to the game especially on longer wipe servers or coop worlds.
Just a funny one I thought of is that when you kill the big robot you can get a "damaged mechanoid core" you can then use this together with circuitry to repair and reprogram it and then with a pretty expensive construction cost you can make a robot bartender for your base that will get you food and drinks dependent on your hunger and hydration level.
This would be pretty much useless in PvP or any combat but just a cool addition to work towards and a tiny quality of life increase and just making your base feel more like home.
