I have followed your suggestion and contacted Dan Davenport: actually, he really liked EVENT and invited me to a dedicated Q&A session which you can read here. Talking to him was a real blast! We went through most of the game mechanics, paying particular attention to the new optional rules and the modular aspects of the system. Dan did a great job with the questions, bringing out some distinctive aspects of EVENT and emphasising the importance of building some additional optional modules which I'm already workin at for the Kickstarter edition.
Thanks a lot for your valuable advice!
