I will also help where and when I can.

Personally, mine follow mostly with yours. However, where my 5% margin of variance might differ from yours is mostly in the pricing. I understand and appreciate the desire to match 95% of the vehicles with 95% accuracy, to be honest applaud even. However, I believe some of the vehicle pricing in the books seems to just be random and arbitrary. So, my hope is that a system can be worked out that can give the versatility to create vehicles in a way that provides consistency, fairness and balance. If you run games gritty and hungry, then you can use this to make unique vehicles that won't break the world but still offer something special to the characters. Same for those who run things with credits flowing between appendages. This can be used to create vehicles that feel above the rest (and actually be) without being game breaking due to the mechanical restrictions. ....ok. That was more a run on thought, than an answer. So....my priorities would be to flesh out the cost for the modular upgrades next. I think you have done a great job with the rest of the mechanical aspects thus far and this seems to be the part that is most in need of attention at the moment. EDIT: Modular meaning the docking clamps and anything else that is TBD. Sorry...long day. 🙂
