Last time I played maru, I had more money then i knew what to do with. Had like 150 bil stashed away. Not too hard to get if you save your money and get a few good guardian kills.
..or they HAVE but would like to make a profit still fighting in the millions/tens of millions PR for several months/weeks and living off of borders that high will NOT happen, and 1 bill only lasts so long...even with bugger all upkeep ships
because income types are relative to each race, a terran might make more cgs than a maru does, but the terran would not make enough money to support any sort of a fleet, while the maru would make enough to pay for the cheap maru ships
maru`s industry mod is lower than terran, but compared to other forms of maru income, industry isnt too bad, just like an agri maru
