Hmm, this is a tall order, because in a way you have opened a can of worms.. what do people actually... want
Personally, I think we should look at the strengths and weaknesses of all the present systems, and come up with the best compromise between complexity and simplicity. Coda is an excellent place to start, but it has issues, such as the reactions, which are mentioned in other threads, etc. Of course getting everyone to agree on what all that is is the hardest part!
Coda is meant to be an ICON 2, yet some things got dropped which people liked. But that said they are both largely compatible with each other, so I think it's something we should aim to do, so that people can have added value from the existing books.
Create a core rules set and mechanics
create a simple character creation process/tree
redesign all the alien templates for the new rules
That way we retain maximum compatibility, but don't create issues down the line with Decipher.
With regard to Paramount, well that's going to be an issue no matter what. But personally I can't see it being any different than these Forums existing. So long as we are not making money from it, Paramount is unlikely to bother us! But it's down to Magnus as site owner to do what he feels is best, as it's his site!
I'll help out if you need me too, I'm fairly good at DTP, Photoshop, and I dabble in 3D too. I play and write a lot of my own games, and i can probably organise a play test group with my players too
