Today's mobile gamers have several options for experiencing immersive gaming action when away from home. They can purchase a handheld console like the Asus ROG Ally or Steam Deck, which emulate gaming PCs but are very costly. The more economical route is to take advantage of an existing smartphone that is surprisingly capable of stunning visuals and fluid gameplay. A mobile gaming controller, like the GameSir G8 Galileo, attaches to gaming phones and provides an alternative to awkward touch controls.
