Free-to-play (F2P or FtP) video games, also known as free-to-start, are games that give players access to a significant portion of their content without paying. Free-to-play can be contrasted with pay to play, in which payment is required before using a service for the first time.
There are several kinds of free-to-play business models. The most common is based on the freemium software model, in which users are granted access to a fully functional game but are incentivised to pay microtransactions to access additional content without spending large amounts of time 'unlocking' it. Thus, free-to-play games are usually not entirely free. For freemium another method of generating revenue is to integrate advertisements into the game.
The model was first popularly used in early massively multiplayer online games targeted towards casual gamers, before finding wider adoption among games released by major video game publishers to combat video game piracy and high system requirements.
