Visionaire Studio is an editor that allows to create point-and-click adventure games without the need of using programming skills. A lot of developers have been using it and still use it with good results.
The Night of the Rabbit, ASA: A Space Adventure, Catyph, and many others have been created with Visionaire. Developers love its flexibility and ubiquity.
We, translators, love the fact that allows translatable strings to be exported in a number of formats. 😀
