Not using the StarCluster ruleset, I bought this as a sourcebook for vehicle systems but didn't find a great deal that was new in that way. I don't have a good feeling about the way that the vehicle statistics scale or the range of technology and vehicle types that they try to cover with unified mechanics. There seem to be almost no manoeuvring rules. I think I'd get more from a widely supported system that has had a lot of designers picking apart, pushing to the limit and adding as needed to the vehicle rules.
Not bad. You have a lot of details that you can compile to construct your own vehicule, calculate its speed.
That means a lot of tables in these 15 pages, few illustrations (one of them is interesting) and very few text.
Needs to be developped.
