One of my favorite things about PC gaming is that you can play with whichever controller you like best. There are controllers made specifically for PC, but if you want to, you can just use a Playstation or Xbox controller. You can even use controllers for older consoles like Super Nintendo or Nintendo 64.
My personal favorite is the DualShock 4 wireless controller for Playstation 4. It’s a form factor I’ve used since the first PlayStation. They haven’t changed it much over the years, so it’s good for both modern games and older classics. It’s also wireless, which is nice for playing on a TV, and the touchpad can be used as a mouse.
