Game Idea

(Mostly) Single player game

 * You build you own power plant grid(s) and productions facilities.
 * You can not interact with what other players have built.
 * You can see what a player has built, but you can not see where it is located. i.e. you can never see where another player is in real life.
 * Maybe I will add a trade with other players but that will be in the future. Maybe an auction tool with at least 24 h time and a fee of 10% of the items or so... hmm... future.
 * Maybe I will add a chat or just refer to some other chat tool.

Walking game

 * Not traveling fast: Solved by letting user has a 20 m radius and all actions require you the have the target location in range for 5 second to be performed. (Note: The code need to keep track of how long existing things have been in range, so when you decide to do an action it might be less than 5 seconds left)
 * Should be suitable if you often walk the same path.
 * You should not have to look at the screen all the time. The should be an automated mode and a sound feedback when something is in range and when an action complete/fail.

Offline mode

 * That game should work even when you don't have network connection
 * You still need to sync to server from time to time.
 * This mean that unless sync-ed you can only use one device, at a time.

Player

 * User has a mobile battery and a backpack to carry things in.
 * All items has a weight per unit. User may carry a limited amount of weight and energy.
 * The user may have to walk back and forth to move a lot of stuff.
 * Material may be dropped on and picked up from facilities or the ground.

"Gameplay extremely Simplified"

 * Build power stations (primitive solar cells at first)
 * Build production plants
 * Collect/bring power and material between cells and productions plats (limited capacity)
 * Improve power stations and production plants (battery=>energy and material storage and speed?)
 * Connect power stations and production plants (electric wire and later conveyor belts)
 * Goal: Improve your power production
