@Yamamato Hi there, and welcome to the forum. Feel free to start your own thread.
I’ve no idea.
There’s a lot of works in progress. Most people on the forums are amateurs with day jobs, or students, or even still in school. Writing interactive fiction simply isn’t the top of their priorities, even if they are working on a project. You’ll find things similar on any site, most WIPs, be they novels, or webcomics, or games, just never get finished. We do it for fun, and people often stop if it stops being fun for them, or if they find something more fun instead.
You get roughly 17.5% of the total price of the game in royalties. Games can cost between $1-$3 depending on length. The Choice of Games sell more copies than the Hosted Games do, and have more exposure.
I’ll take public sales figures as listed on facebook pages.
Heroes Rise, is one of the best selling games, and it sold 20,000 games in a year. That would have made the author $10,500 if he’d been on the hosted deal. You’ll make a lot less than that. Also keep in mind that there was a period where Heroes Rise was on sale for $1 which will have inflated the sales figures.
Life of a Wizard (the stats are at https://www.facebook.com/LucidsGames) had sold 4000 games in two months. At $3 a game that’s 52.5 cents a game to the author, and roughly $2,100.
I would guess that sales figures tend to peak in the first few months before dipping down to far lower figures.
Of course your sales figures will also depend on how much advertising you’re willing to do, the content of your game, etc. And the price will vary depending on its length, and whether or not you have pictures, and quite likely the quality too.
I’ll say you probably shouldn’t expect to make as much as Life of a Wizard, since it is a huge game.
Start short. Start simple. Write about what you love, what interests you and you’re passionate about. The most important thing is to write a completed project. Get it finished. If you have something finished you’re already ahead of most of us.
There’s a wiki http://choicescriptdev.wikia.com/wiki/ChoiceScript_Wiki The guide on http://www.choiceofgames.com/make-your-own-games/choicescript-intro/ is good too. If you own any of the games on google chrome you can read the code there. Or on the main site just browse to the scenes folder. So https://www.choiceofgames.com/dragon/scenes/ will show you the code. (Read the txt files and ignore the rest.)
