Eric,
The main differences between the FASA and LUG RPGS can be summurized as follows:
TASK RESOLUTION
FASA uses perctilile dice (D100) to resolve tasks. Players typically must roll against thier skill rating or an atteribute (in the case of combat, the average of a skill and an attribute). In some instances rolls are not required due to have a skill greater than the difficulty of the task.
LUG uses a mutiple D6 system. With the player rolling a number of dice equal to an attibure, keeping the highest, and adding in a fixed value for skill level. A drama die adds a bit of randomness with a drama die-a d6 that if it rolls a 6 allows the player to add in the next highest roll.
SKILLS
Are similar from one game to the other. The big differences are the scale (1-100 for FASA and 1-6 for LUG), and the fact that LUGTREK groups skills together into categories with specilizations rather than listing everything as its own skill. For example, in FASA Deflector Shield Operation, Starship Helm Operation, and Starship Weaponry are all separate skills, but in LUGTREK they all are specialities of Shipboard Systems skill. This allows characters to get a basic proficiecy in several FASA skills by taking fewer skills in LUG.
SCOPE
FASA TREK was set in the time of TOS, eventually focusing on the time of the Films. Although two supplements for the TNG era were produced, neither were widely distrubuted, or really gave enough information to run in the TNG era. LUG TREK on the other hand, produced most of it's products for the TNG/DS9/VOYAGER era. An excellent TOS CORE BOOK was produced, and a MOVIE ERA sourcebook was planned but not realeased before LUG lost the rights to Star Trek.
GAME SYTLE
FASA TREK at first tried sor a style of play tohat would mimic the orignal TV series. After TWOK was released, the game becme more and more militaristic/combat orientated. LUGTREK is a more modern game and put greater emphasis on storytelling and cinematic style of play.
