Destiny 2 has been available on consoles for a while now, but it's not coming to the PC until next week. It sucks having to wait, yes, but the upside is that we get our very own launch trailer—and it's time to watch. 

The PC version of Destiny 2 is going to be functionally identical to its console cousins, but it will bring some distinct advantages to the table too, including uncapped frame rates and support for 4K graphics if you have the hardware for it. I'd say that playing with a mouse and keyboard counts as a pretty big plus too, but your mileage may vary on that point.
