Speaking of which, GTA Onlines whole "business" system is basically a wholesale rip off of Scarface main gameplay loop, but it's actually fun. (or at least more fun that GTA Online)
You buy some drugs. At the start you're buying from small time suppliers in Miami but you quickly begin having to make deals in the Caribbean and have to smuggle it back to Miami avoiding gangs and coastguard. After you've smuggled it, your fronts sell it. Then you have to go around collecting the money from all your businesses while avoiding cops and gangs.
What made it more fun and rewarding was instead of being given weird missions and having no choice in vehicles to do said money runs, you're basically choosing which areas to collect from and were able to choose from any vehicle you'd bought up to this point. Imagine if GTA Online actually let you use the vehicles you spend millions on to actually play the main loop, it might actually seem like you're building towards something.
Here's a quick vid showing it off.

Scarface even has the exact same money feature as GTA Online where you need to put your money in a bank (launder it) to save it. Otherwise if you get killed, you lose everything you're holding.
It's why I've kind of reached the point of not caring about GTA VI. If the rumors of "Americas" are true, it's just going to be a prettier Scarface with way more boring cutscenes, dialogue, and probably shitty griefers and microtransactions getting in the way
