If you're looking to enjoy the best games on the Nintendo Switch, there's simply no substitute for this versatile console—or its expected successor, the Switch 2. Getting started with physical games is a breeze; just insert the cartridge and play. Unlike the top titles on the PS5 or Xbox Series X, most physical Switch games are playable immediately without requiring additional downloads. However, digital purchases and titles accessed via Nintendo Switch Online typically come with lengthy downloads. Fortunately, there are various methods to enhance your download speeds.

Clear Your Network
