SpaceDogsbody/FamilyVersion

• The random board layout and probably the board size
  
• The mining of resources from asteroids (and the three-at-a-time onboard limit)
  
• Fulfilling missions (probably just Industrial Shortages)
  
• The pirates moving around the board (which is the game's most unique feature)
  

• Most of the different kinds of space (basically leave a bunch of asteroids, a bunch of mission spaces, and a few stations - or combine the last two)
  
• Most of the upgrades (I think a Laser in some form is probably still worth having)
  
• Most of the complexity of how pirates move
  
• The reputation track, probably
  
• The distinction between onboard cash and bank account
  
• Tourists and passengers
  
• Face-down tiles, and the distinction between green, yellow and red tiles
  

• Say 40 mission cards, 4 asking for each pair of resources from Cubon (paying 2), Cylium (3), Isolene (4), Starbon (5), Diamantium (6)
  
• 25 tiles:
  
  • 6 stations which provide a mission-card slot and the opportunity to buy a Laser
    
  • The Pirate Lair, which starts with 3 pirates on it.
    
  • 20 asteroids, 2 providing each pair of resources (actually, that's too many: leave some of them down at 1 copy so there's 25 tiles total)
    
• Start of each player's turn, that player chooses a pirate to move and a player to move it towards. It moves one space towards that player. No restrictions on closest player, or whether the target already has a pirate in their space, or which axis the pirate prefers.
  
• Then the player takes 3 actions, from the set of:
  
  • Mine one resource
    
  • Fly one space
    
  • Fulfil a mission / buy a Laser
    
• Moving into a space with a pirate, or a pirate moving into your space, means you have to roll. On a 1-5, pay the pirate $2 or a resource tile.
  
  • One laser takes this down to only paying on a 1-2. Two lasers protect you completely.
