I worked for a time as a "pool writer" for Last Unicorn Games on their Star Trek RPG lines. They put out some nice products (I'm particularly fond of the time travel sourcebook All Our Yesterdays). Unfortunately, Last Unicorn ran into various problems that held up the publication of a number of projects. They were eventually bought by Wizards of the Coast and lost the Star Trek license to Decipher shortly thereafter.
Wizards decided not to publish the remaining products Last Unicorn had completed, so the rights reverted back to the writers. I'm posting my material so fans of the Star Trek game can have a chance to read and use it, if they like. Please note that these are my final, unedited drafts and this material wasn't approved by Paramount, so it can't be considered "official". Otherwise, enjoy. If you like it, feel free to drop me an e-mail and let me know.
