Just a list of odd add-ons, which i think would add some options for players to (mostly) have fun with. haa!
1- Id Plotter- This object will identify debris from mining and exploring, such as metal or wood particles, and give information about the civilization who handled the material. This will allow players to collect pages of lore and research the different settlements and even individuals dotted around the generated world. It could even reconstruct the material into a collectable object, such as a dagger or pot for display.
2- Bacterial Scanner - the player holds onto this object much like a mobile phone, and it scans their entire body for infections, and gives information about what they have and how to gain the remedy, complete with ingredients needed.
3- TechnoSketch - the player freely draws out plans for objects, tools, clothing etc, and prints them out. The plans can them be scanned through the physical materializer, to make them into real objects.
4- Linguistic Translator - this object will translate any page of strange text, or an audio item into a chosen language. There could be hundreds of pages and cds strewn across the world, and some could even lead to mysteries for the player to uncover.
5- Bio-Matter Combiner - this mixes up different living items, to create something new. For example, you could combine a carrot sapling with a maple sapling, and create a carrot tree.
6- Test-Subject vault - This object will create creatures from anything living, such as raw meat or saplings. there could also be cage objects to display your mad scientist's creations.
7 - Automated Tasker - This could be the brain which commands certain other robots. they could be capable of undertaking various tasks, such as farming, building etc. The tasker could be interacted with, and programmed to command the smaller robots to perform these tasks. This would be cheaper on your resources that human allies, with the cost of interaction. balancing out the costs.
