So the various Star Wars sourcebooks have usually introduced some extra rules not found in the CRB.
- Base building
- Mass combat
- Battle scars
- Old west gun duels
- Homesteads
- Bounties
- Animal companions and riding
- Crafting (including for armor, weapons, gear, cybernetics, lightsabers, and ships)
- Contact networks
- Computer slicing
- Explosives
- Squad/squadron
There's probably more I'm missing, and more to come. Not to mention the numerous charts, such as social encounters, combat in different environments and settings, encounters in urban settings, encounters in the wilderness, space combat, etc.
How do you think they'll introduce rules like these to Genesys? Release an 'Expanded Rules Sourcebook,' maybe? I figure the animal rules may have to be in the book in some form, seeing as they're doing a fantasy setting.
