Star Wars Universe has all kind of bounty hunters, inclusive droids. Ig88 are a family of droids built for assassination, the most famous is ig88 B (The droid from esb). Ever I have wondered what use of money could make a droid? Well, Ig 88 has a space ship, he spends money in weapons, grenades, batteries, he could listen to music and buy cds or so on. But he can´t spend money on food and drinks, he is a machine.
If a droid is an art collector he could buy statues, vases, maquettes, books, holocrons, etc.
But why these droids need money? What is the ultimate use of monet for them?
