I have been reading a lot of Star Trek material over the past few days. It has led me to consider whether you would prefer something that is purely Star Trek, or something that is purely 2d20 system.
The advantage of the 2d20 centric system is that you could use it with Conan, John Carter Warlord of Mars and Mutant Chronicles as well as Star Trek.
The core oracle would be the same as would the rules on using momentum/ complications/ threat. The difference would be the supporting material. I can either gear it precisely to my vision of Star Trek, or I can make it broader, so it will cope with all 2d20 system games.
What would you prefer?
