A Game Streaming Service allows players to access and play video games over the internet without needing to download or install them on their devices. This service streams the game directly from powerful servers, enabling users to play on various devices, such as computers, tablets, or smart TVs. Popular examples include NVIDIA GeForce NOW and Xbox Cloud Gaming. These services often operate on a subscription model, where users pay a monthly fee for access to a library of games. This model provides flexibility and convenience, as players can try different games without the commitment of purchasing each one individually.
