Here’s the updated file for 3.1. I’ll keep this here as a post for a bit while testing it out. I’ve almost certainly missed something. For some reason this file is twice as big as the old file. I remember getting the file this big before but I can’t remember how I got it smaller.
Next job is to convert the Player’s Handbook to the new Tech Challenges. That will take a decent amount of work to iron out the crafting rules since that’s a very fiddly beast to get right. I’m going to try and make that process a little more friendly to solo play. My son spends hours doing his best to break the crafting rules. I remember doing the same with Night Hawks and Battletech so I guess I can’t complain.
