Star Chart (Ideas):
Map (array of objects called areas of space)
Areas of space contain: Mothership, planet, enemy fleet, ally fleet. If it contains neither of them then it can be considered empty.
(If using mouse support and only having the area of space to interact with) One click will select mothership, the next one will select ally fleet then enemy fleet then planet (Have a hierarchy of important selectable objects to view in areas of space).
Can move fleet/mothership N/E/S/W a certain number of spaces or move to specific coordinates.
Example: Generate a 100x100 array of these objects, one mothership, a specific number of planets and start the game around the mothership where you can send out fleet to scout/explore/find habitable planets/engage in combat etc.
Planet:
Have one abstract planet with multiple types?
Planets have resources?
Planets can house critters?
Send in army to defeat critters to make planet habitable?
Pitstop for ships to repair or refuel
Other dangers? (Lava world, toxic atmosphere, ocean world)?
Have basic colony on planet that handles all landing/departing of spaceships?
