No no you didn't write too much at all. I enjoy reading posts like this! I was just hoping you didn't feel pressured to type a lot... I hope that makes sense!
About Ren'Py, you can do it!!! So far, everyone I've seen try Ren'Py succeeds/has had a good time with it. Ony gave some good tutorials, I think I've followed some of her stuff before.
I've also wanted to try RPG Maker but idk where to start D: RPG Maker seems harder to use than Ren'Py...
