I kept the same format as my original illustrated rules. Sadly I ran out of space for two Variant rules I came up with. I might revise the sheet later if I can get them to fit. I wanted to keep the rules to 2 pages so it prints front to back without requiring to be folded.
Here are the rules. Feel free to comment on these and the expansion rulebook if you find any problems or confusion.
Known Universe Don't keep the cards face down during setup. Flip all cards face up.
Long Range Scanners Add a modified Turn Sequence 1 back to the game.
Flip Over the closest planet to your token's location. If two or more planets are equal distance, player chooses card to flip.
This rule allows the player to "scan" a system before moving and helps remove some of the randomness of trading.
EDIT- I uploaded a new version 1.1 of the manual that is reformated to include these two variant rules. Plus made a new logo for fun!
