`  == Kilometers (K) and Metres (M) ==  It might be possible that K mean Kilometers and M refers to Meters in-game but they are DEFINATELY not to scale with the current measuing system on Earth.  To argue that the game is ``unrealistic`` because distances between planets are ``only`` 20km is ludicrious. Marathon runners RUN 20kim all the time on Earth!  The official website stated planet Mahattan as 12,000+ km in diameter is also definately refering to km as another unit of measurement differing form kilometers. America alone is 9 million km squared in Area!  Bottom line: K,M,km in-game do not refer to actual ``kilometers`` or ``meters`` we used right now.`
