What causes the ideas to sit there and not come out onto the page? I can't find the key to open the bars that keep those ideas trapped. It's like I can't translate them into english when I try to write it down. For example, right now I'm working on this reworlking of how spaceships work in my campaign world. (3.5e d20 system) I have taken an idea from the Farscape RPG and decided to expound on it and make a really flexible system, and the mechanics are amazing. I can see it all in my head. Various stats and ships. I can see the rules in action in my head, I can see the two systems working in conjunction. One a simple system that requires no visual reference, allowing for descriptive storytelling style of play, the second miniatures on a hexboard with flexibility enough to allow for anykind of focus you want in your game. Amazing stuff. Can't write it down to save my life.
It's an odd thing really...
