@ZardoricI'll probably be using a simpler system for money - If you've heard of World of Darkness/Vampire The Requiem, that sort of system.
There'll be "levels" to finances - you'll have a certain amount of points you can split between money, assets, connections, retainers, ect. at the start of the game to keep it simple. Fame will play a big part into these.
You might need one point to keep a knife, for example, since they're cheaper to get hold off. To own Power Armour you'd need 3 points, or something, just as an example.
I have a roleplay running already with specific prices ect. and I think that's all I can manage on that front.
