EDIT:
2 interesting things I found out about this planet_special_weighted_chance table:
- An option that has been considered before dev's settled on the concept of Wormholes (#1):
- "weakness in fabric of space", adding +2 parsec/turn between 2 systems.
- "minor race", a civ of 5 pop and a small fleet that will defend their world when you find it.
