Imposing a time limit of 1 month is needlessly ambitious. If we succeed, we'll be able to look back, point at the tileset, and say 'we made that in 1 month'. But really, why rush? I remember a Liberty freight ship destined for Atlantic convoy duty being built in just 1 week, as part of American industrial propaganda during WWII...well, truth is, some Liberty ships tended to break apart in half in stormy weather. Why don't we just make 2 months the default time limit so there isn't an unpredictability over extensions...(and if you go pass a 2 month deadline, you can blame me ).
