Wha-hey now, this is actually somethin' I want to toss my two cents in for. Always happy to help a fellow spaceman make a few spacebux.
But first, as to this gentleman's fine points slandering a good profession:
Its not Robigo is fine (apart from it being far too easy for far too many credits) unless you mode swap to refresh the list of available missions.
Then it's exploiting.
I.e Using a glitch or game system to gain an advantage not intended by the game's designers.
same exploit is used to gain rank with Feds and Imps.
same exploit is used to increase BGS inf for factions.
Looks like Fdev have left this exploit in for 2.1.
So they had a mission system that is exploitable, which they updated but left the exploit in.... way to go Fdev.
Fdev thinking :-
I have a fence around my vegetables in the garden to keep out the rabbits but its got holes in it ... Hmmm I know !
Ill paint it, that should work.
Or could it not more easily be explained that they intended it? They had a chance to change it, but intentionally left it in. To me, that seems an awful like game design choice on their part. Smugglin' is a tough gig, cops always on your back, risk of life and limb. Makes sense it should pay out well. Trading is straighforward, easy, safe. It's all a tradeoff of risk, reward, and 'action.'
Now, back to the point, if ya' wanna make bank, yeah Robigo is a good gig. If you got the ship to get out there and the time to lay down for a run. Alternatively, just do what you have fun with. Right now, there's a few CG's running that could get you a quick buck for just a little effort. Look up Skvortsov Orbital in 63 G. Capricorni. Take some recreational trade goods there (Beer, wine, tobacco, liquor, narcotics, the good stuff, etc.), sign up for the CG, sell em off, and repeat for all the profit you want. Easy money.
