I read the follow-up article. This new title (assuming they finish it) actually looks interesting, or at least the described characters look interesting. Only one teenager in the foursome, and one 40-year-old guy. Give Square/Enix credit for defying convention and trying something new. As for the gameplay, who knows? Sounds like a dungeon crawler with guns. Not a whole lot to go on.
Of course, I'm not pleased that this "surprise" had nothing to do with Chrono, but I honestly wasn't expecting it to be anyway.
