Articy:Draft
Articy:Draft may well be the best interactive authoring tool created so far. We didn’t have time to play with it in closed beta, but the software is now up on Steam Greenlight, and you can vote to make Articy:Draft available on Steam.
The current cost of the software runs close to $500, but if it goes to Steam, the cost should decrease. If you subscribe to Game Developer magazine, you can read a lengthy review of the software written by Tobias Heussner (unfortunately, the article hasn’t been made available online yet). Google Articy:Draft for more information, and follow the developer, Nevigo, on Twitter to stay up to date with the tool.
The next time we’re back on an interactive project (or during a hiatus between academic semesters, if we’re ultra-ambitious), we plan to be taking a long look at Articy:Draft.
