This book a mash up of Cepheus Engine rpg with Fasa Star Trek simmered over a coating of old school fandom. Note that this is only original Trek shows not the Calvin time line movies, or Star Trek Discovery. Star Trek: Alpha Quadrant is an interesting compromise between FASA Trek & original Trav erm Cepheus Engine rpg Star Trek: Alpha Quadrant is fan production but its very good fan production.
Star Trek: Alpha Quadrant is basically Cepheus Engine rpg Trek taking PC's from beginning career paths right through to serving on the star ship of their own as bridge or away crew. And its done with the usual Cepheus Engine flare.
