So you want Square Enix to make you another Chrono Game, and you're going to use a bunch of people's signatures tied to "Give us Chrono 3 or we'll do another petition", aimed at a company that stems from Japan (no they aren't gonna make a CT 3 for everywhere but Japan) and could really care less what you think. Aside from a few art sites, we don't even know what the fanbase is like in Japan. Sure the Dream Team loved it, but... yeah.
There are as many Chrono Trigger-related petitions out there as there are Street Fighter II remakes, and even less sequels to Chrono Trigger than there are to Street Fighter, which is saying a lot.
If you want to send a message, speak the language of the dollar bill and don't buy into their other crap.
