Is a sole developer getting help from a larger companies normal? If so, what companies?

Hi,

I have been writing my own RPG system for a few months now, and it is getting to the point where I would likely publish a book. Who do I even talk to in order to figure out what to do at this point? Game development (in my case, both writing for table top and video game formats) always seemed like an insurmountable mountain to me, and I don't know anyone familiar with games.

I have been a fan of Obsidian games for a long time, and want to make games like they do. Where do I start?

Thanks for reading,
