The short answer is, you could publish a ChoiceScript game in another language, but you probably can’t charge money for your completed game.
We do license out ChoiceScript but the process is inaccessible to most casual game writers: If you wanted to use that option, you’d be responsible for all of the work in terms of building a working app, submitting it to stores, setting up a developer identity on stores, and so forth. We charge a 25% fee on all revenue generated by ChoiceScript games for this option (so if you produced a game that made $100,000, you would need to pay us $25K).
Because there are costs to us in terms of time, legal fees, and attention to licensing out ChoiceScript, we would require a $20,000 minimum fee for the first year, payable at the time we enter into the licensing agreement. That would be an advance on the license fees, so if you produced one game in the first year and it made $100,000, you would pay us $20,000 at the time of signing and an additional $5000 once the royalties due exceeded $20,000, for a total of the $25K that represents the 25% fee.
