The fencing system in gta 6 is going to separate the rich players from the broke ones ( my analysis )
In gta 5 you finish a heist and the money just appears in your account. Done. No thought required. GTA 6 isn't doing that. The extended look showed that after you rob a place you still have to move the goods and sell them through a fence. That's a whole second phase most people aren't thinking about hmmm ... So you rob a jewelry store. You chose to crack the safe instead of blowing it so you kept the full value ... alrighty ... now you're standing outside with stolen goods, cops are searching the area, and you need to get across the map to someone who will buy them. Do you drive straight there
