Usually people say that you need 3 roles to make a project for a game: a writer, a ilustrator/animator and a programmer. I would add more 2: a manager and a advertiser/social media.
This is not a criticism, but a suggestion. Take a position in which role(s) you will gone act. If you be the manager, you should already have a roadmap, a delivery plan and the goals. If writer, nothing stop you from already write and test it on a prototype, Twine is great. Some creators releases games completelyin text only. It's a nice way to test the concept. For advertiser/social media you should already have a well know profile in some adult games portal, or a blog somewhere.
I feel people being a little bit hostile, that may be because take the illustrator/animator role implicate in a massive workload. Hours an hours to make images that will be consumed in seconds. If the other roles fails, everything turn in garbage. Who ever passed by this, is not happy about it . Safe programmers already have their base-code done, just make some changes, but beginners will also have a lot of work.
