Over-oversimplified version of Shadowrun.
The year is 2070. Magic is real, and lots of people have been born into different metatypes (races) like elves, dwarves, orcs and trolls. Monsters exist as well, even dragons.
Technology has evolved to the point of being able to directly interface with your brain, and you can get body parts replaced. Want chrome cameras or cat's eyes in your skull? Yours for the right price.
Governments have fallen apart and megacorporations pretty much run everything. However, some things require independent contractors (aka deniable assets). Corporations employ Mr. Johnsons to hire on shadowrunners to do the things that megacorporations want done but can't legally pay people to do.
The game allows for an awful lot of leeway, but here's some basic classes:
Street Samurai: Most of your body has been replaced with cybernetic enhancements and you are a killing machine.
Mage: Either a hermetic (books and tomes) or a shamanic (more animistic) approach to magic, but you have the Gift and you can cast spells.
Adept: You have the gift for magic but in a different way. It lets you jump higher, move faster and so on. Think kung fu monks and chi.
Hacker: Known as deckers in earlier editions, Hackers go through the Matrix (yes, like that Matrix, but Shadowrun had it first) and worm their way into systems
Technomancers: Like hackers except that your brain is capable of going into the Matrix without any sort of artificial aid. You just concentrate and your brain handles the rest.
Rigger: You control drones, either vehicles that people ride in or various types of robots.
Face: The charismatic negotiator.
It's also more than possible to be a mix of stuff, but you tend not to be as good with a mix than if you focus on one thing to be best at. If one of those calls out to you, it may be best to ask about that and learn about that part of the world.
