My group has one PC who has quite the high Lifestyle value, so they thought it would be clever to make all purchases go through her. For now I’ve told them that they may transfer assets to her, but regarding the cashflow, I’ve told them, I’d ask in the forum to check how other GMs handle this topic. For the time being I argued that their PCs barely know each other and probably would hesitate before tranfering large sums to each other, but in the long run, I’d want to know how you guys handle this.
Considering how much money the players have, if they put it all together, they four of them would almost have a combined cashflow of 50 each session, if they pool it together.
