The Early Years

The rules, as they stand, are mainly suited for battles set after the yahren 6400, when technology was developing, ships were expanding, and weapons were getting more deadly. But like everything, the modern era has to grow out of the old. And these rules are designed to fill that gap. The Early Years period of BSG lies between the yahrens 6000-6400.

This article refers to Module Y1 The Early Years, but as you will see, because BSG does not use many of the the systems from SFB it is quite short. If something is not listed here, then assume that it has not changed.

The following is a list of rules references in Module Y1 that should be used:

(YC12.0) Changing Speed in Midturn
(YD6.0) Fire Control Systems
(YD8.0) Critical Hits
(YD17.0) Tactical Intelligence
(YFD0.0) Drones - note that there are no changes here save those listed on the table below.
(YG4.0) Labs
(YG24.0) Scout Functions - Some ships may have scout functions
(YJ2.0) Shuttles - generally no changes, but the stats of some shuttles have changed.
Please refer to the Master Fighter Shuttle Annex for more details.
Note that MLS-Y and MSS-Y shuttles were larger than they are today, but otherwise functioned pretty much as normal.
(YK0.0) Fast Patrol Ships - these were around, but have no changes
(YM0.0) Mine Warfare

Phaser 4's do not exist at all.
Phaser 1's are in short supply, and mainly outfit bases and capital ships.
