All of our best games were forbidden in one way or another. Actually, pretty much everything was forbidden—whether it was fun or not. There was a sign at every corner in Gropiusstadt. The “recreational parks” between the high-rises were really just sign parks. And most of the signs were directed at kids, prohibiting one thing or another.
