Oops, I put this in Publishing, but I think perhaps it would be better here. I'll move it here and then go take it out of Publishing.
I kept tinkering with RPG ideas from time to time, and my wife encouraged me to get it down in a Word file, and from there I just kept writing, and, again encouraged by my wife, it turned into a whole 178 page game book. I have no one yet to playtest it, I don't have a lot of neat art, I haven't decided if it should be published digitally or what/how. I'm hoping to find a few people to communicate with who have some experience with this sort of thing so I can get advice about what my next step should be. Anyone interested in talking about it off-thread? If so, let me know.
Play that sucker!
That, I reckon, is the next step.
Then, once you do that, get someone else to play it with just your text to guide them.
Congrats on getting it written, that first step is a huge one. Hard work is waiting ahead.
Good luck!
