Its just not useable in a realistic manner. Great for... inspiration? For making your mouth water at options that simply are not rendered here well enough to be put into a game without obviously breaking something...

Genuinely heartbreaking, snark aside. There are seriously so many cool ideas in this little book, but this is better taken as a standalone "Vehicle Creator" for generic roleplay use than as a contender for Starfinder as a vehicle expansion handbook.

The problem is the organization and readability leaving something to be desired, and more critically very little of what exists in the numbers of this book is actually balanced against starfinder rules and balancing curves. It is balanced against itself with somewhat arbitrary credit values serving as the base for the math in the rest of the text.

I want to use this so bad, but not if it means throwing the core balance of the game out the window.
