Go and publish them as books first.
A good book does not necessarily translate well into a good video game. You may find that you would need to cut out a lot of the story or even have a brand new story within the same universe to make it into a game which people are willing to pay for.
I have working drafts of a novel and its video game adaptation - and they are 2 completely different stories set in the same universe, because just walking and talking will not appeal to players.
Yep. Thank you Envy. I will public first book. The only one was translated. It took much time and money to translate it.
Of course game story line is a different from book. I changed and added many things. But it going fast and easy. I already have Universe with lands, seas, creatures, countries and events. To make game story on it base - real fan. ;)
Also, a book can give you more freedom in writing and you're not constrained by art assets. In your case, fantasy can sell pretty well as a book with the correct marketing.
I guess my case is unique where I think my game version will sell more than the book could ever sell, realistically.
Its gameplay can appeal to a lot of players and is very GIF friendly, while the story by itself may not pass Richard & Judy's stringent requirements if it was a book (and it pretty much has to, if it's going to be a best-seller).
