Additionnally, I'll probably do some calibrating depending on the power of
the computer the game is running on. Basically, we have a "bench" function
which exacly does this -> run the game for 10 seconds and see how much it
can compute. I could use this as an input in the map loader and say
something like "if computer has a power of say, 13, then the maximum
fighters it can handle at speed 50 is 9000". The idea is just to calibrate
the function "max_fighters = magic_constant * computer_power / speed". The
only thing to figure out is "magic_constant".
