Alright, first up.[@WilsonTurner] Sorry that I never answered you in that PM.
Tramline idea is fine for a book or a more cohesive RP.
This game has far more lax regulations. You can practically make any ship so long it isn't too OP.
Balance is established by point costs and such in general.
Just look over my fleet. I have warp capable ships and torpedoes plus a superluminal railgun. Take it easy.

Second, I haven't even looked over Unknowable's profile so he put it up to the character sheets too early.
Granted, I am a reasonable guy and doubt there'll be many issues.

Third my comp is broke so don't expect me to make longwinded posts on my phone.:lol
