Ren'Py

While it wouldn't appeal to those who don't already have a background in the Python programming language, developers who want to be able to put out software-mediated stories that can run on a multitude of devices should certainly look at Ren'Py. Visual novels are a type of video game particularly popular in Japan that generally involve animé-style character illustrators coupled with branching plots. Many of these are dating simulators, which feature a character who tries to win the heart of one of several choices they're given in game. Nevertheless, the Ren'Py engine doesn't hold developers down to this formula. Those who already have art that represents a variety of emotions can import it into the development studio to generate plots based around any script. Since the game engine takes care of opcode compilation, developers won't have to worry about making separate visual novel distributions for each type of system software that gamers might have. Developers can also provide multiple language packages, which should aid those working on simulations they'd prefer to offer to an international consumer base. While a few small examples do come with the package, developers will have to create all their own art in most cases if they wanted to craft a complete visual novel. Those who find themselves stuck might want to consult the extensive documentation, which is available in both English and Japanese. Since the plot scripts for games feature a sort of screenplay-like syntax, it might be easy for those who don't code to still write the script for another developer. This should make it simple for those porting a manga series to a visual novel to recycle as many assets as possible. The Ren'Py engine attaches itself to the finished game, which means developers won't have to author any subroutines for saving games or rolling back to previous points in the story. There's also support for DLC packages compiled into the studio itself.
