CrashlandingRL - You are a space courier. While delivering some strange big box you was attacked by pirates and had to try to perform emergency landing that turned into crashlanding.
While trying to maintain shields on maximum you burned all the fuel, which is uranium, and burned all the ship's plating, which is titanium.
Basically you are doomed. There are no hypernet relays on this planet. And there is no sentient life.
Before giving up you decided to examine the cargo. The box contained experimental multimaterial 3d printer.
You connected the printer to ship's computer and found that printer is loaded with blueprints of interchangable robotic parts!
Another piece of good news is that you have the matter scanner - it can show direction of more or less big deposit of given matter.
Here starts the game. You print your first robot with metal garbage found in the ship. Robots are dumb. You can only program them to move by given route
and perform basic tasks, like mining or gathering.
Your tasks are:
1. setup routes to gather metals required to build more robots
2. take care of your food and water supplies
3. protect your robots and yourself from the hostile local lifeforms
4. setup routes to gather an uranium and a titanium
5. repair and refuel the ship and leave the planet!
p.s. may be a little too big for a 7drl, but 7drl can be a good start
