A bit obvious, but you need to choose your gaming platforms. That will affect the size and arrangement of your gaming room. Consoles like PS5, PS4, Xbox Series X, and certainly Switch have a small space footprint overall, and typically only need two wires to work. You will need a place for your controllers, though. Add a PC and things get more complex, even if it’s a gaming laptop. For serious gaming, you’ll want the option of a full-size keyboard and a good gaming mouse, and those require large-ish surfaces to work on. And since everything’s online now and gaming’s an always-connected hobby, you want your game room to have good-quality internet connectivity. You should invest in a good router so that all of your gaming devices will get a stable Wi-Fi signal, or be able to connect via Ethernet if you want the best connection for multiplayer gaming.
