Re: Star Trek/Starfleet Battles; advice, opinion and possibly IC
Modiphius's 2d20 is almost unplayable. I can't say anything good about the Star Trek system, except to say where it's not as bad as their previous Conan system. Maybe they have the right feel or tone, but that's all they get right.
Where No Man Has Gone Before 2.0 is a free fan-made Microlite20 mod. I rather like it, it fits a regular or a comedic Trek game. It has enough of a starship combat system that it could work for this.
Far Trek is a fan-made 3d6 clone of WNMHGB2, it's bit more complex and nerfed, and sucks a bit of the fun out. Switching a straight d20 distribution to the bell curve of 3d6 while nerfing other bonuses means most checks become easy failures. It's hard to do anything well in it.
I was the second-last person using Brygun's d6 system (hi!). TBH, I mostly just used the results as a guideline for GM fiat. It's a bit like flipping a weighted coin to make a decision in an otherwise freeform game.
I might be the only one, but I have a perverse desire to see Doctor Who: Adventures in Time and Space (Cubicle 7's Vortex system) used for Star Trek. It's rules light has easy options for making new aliens, androids, and psychics of all kinds, and has a focus on chases, non-violent resolutions, and technobabble solutions, so I feel it's a good match for Trek. The combat system is rather limited, so it wouldn't fit a military, starship combat setting very well. Anyway, a good Star Trek RPG doesn't necessarily have to use a Star Trek system.
