Yes, that's exactly what we are saying
We are asking for the Particle systems to be enhanced so that Missiles can spew particles more effectively, and the same engine can be used for thrusters on ships, Nebulae etc
There are many ways of doing it, depending on what you want to do. Kalthireth's idea is a good one too, but I think it all boils down to needing more flexibility in the particle system
Flipside
Edit : Yes, i know there is a particle spew system already for weapons, I haven't used it, so I can't comment on it, but I think a more advanced system would make a lot of things easier/better for modders
