yes, and i am now the first girl who is a gang boss !
well it is simple, same as complex compounding by only troops.
you need to keep accumulating 1/2 of your attacks income as future and the other half buy more men, and keep attacking, tell you reach the satisfying equilibrium self point plus develop the stores, the major mistake most player do is that they want more drugs from the game while the better is to keep increasing and upgrading the alcohols as the following ratio:
1 drugs : 3 weapon : 6 alcohol
keep developing
AVOID direct fights with other armies
some times you need to f...uck an enemy army but its ok, as you do, they will come back and desroy yours - no problem, begin from your safe storage accuomultaing men from scratch
play between 3 hours to 6 hours daily
