Jesus. Do you guys not read anything? They said 1am CET!!!! 1am Central European time which means Germany, Poland, Czech Republic, Slovenia, Slovakia, France, Netherlands, Denmark, Luxemburg, Belgium, Liechtenstein, Austria, Italy, San Marino, Vatican and what have you. So where exactly are you? What time is it? You got your answer. Either read the FAQ or just check the countdown on GOG or Steam.
Lol... seriously? Those guys are a weird bunch. I bet you that that wasn't meant to happen but someone coded the thing to start just at the 31st and not at a specific time and that is why we get it an hour early .
