I keep reading info about S.T.A.L.K.E.R. and they keep saying that the world be 30 square kilometers. In the past I have often come across mismeasured areas (I'm a physics major and surface area is something I have to calculate quite often...). Do they mean a map that's 30 km by 30 km (30 km)^2=900 km^2 or do they really mean ~5 km by ~6 km = ~30 km^2? The former would be immense and sort of close to what you would expect from a real city and surroundings, but the latter is on the same scale as Far Cry was. So does anyone know what they really mean by "30 square kilometers"? Part of me hopes they did the wrong calculation and give me a huge world to play in, but a part of me just wants to know that people actually can calculate surface area properly. ...and that's my totally unimportant and highly irrelevant question for today.
