Classic gaming and old school gaming, is the playing and collection of obsolete personal computers, consoles, and video games. Usually, retro gaming is based upon systems that are outmoded or discontinued, although ported retro gaming allows games to be played on modern hardware via ports or compilations. It is typically for nostalgia, preservation, or authenticity. A new game could be retro styled, such as an RPG with turn-based combat and pixel art in isometric camera perspective. Retro gaming has existed since the early years of the video game industry, and was popularized with the Internet and emulation technology. It is argued that the main reasons players are drawn to retro games are nostalgia for different eras, the idea that older games are more innovative and original, and the simplicity of the games. Retro gaming and retro computing have been described as preservation activity and as aspects of the remix culture.
