Freeciv in the context of Proprietary software

A browser game is a video game that is played over the Internet using a web browser, typically without the need for dedicated hardware or software installation. They are sometimes referred to more specifically by their format, such as Flash games or HTML5 games. They are generally free-to-play and can be either single-player or multiplayer. It is not necessary to install a browser game; simply visiting the webpage will run the title in a browser. Some browser games were also made available as mobile apps, PC games, or console titles. However, the browser version may have fewer features or inferior graphics compared to the others, which are usually native apps.

Browser games have existed in various forms since the origins of the open internet in the 1990s. However, the 2000s were a "golden age" for the medium, and a great many were created with Adobe Flash during the period. The 2000s also saw the rise of social network games such as FarmVille, and the web ecosystem of the time was a "creative vortex" of rapid iteration and development, which had a huge influence on independent video games. Ultimately, the decline of Flash as a format and the rise of mobile gaming in the 2010s brought an end to the scene, though there have been more recent developments such as .io games.
